OVERVIEW: Talent Predicts Wins, so how did we do?

In the SEC this year, talent based predictions were down when compared to previous years. In-conference games typically run about an 80% correlation between the higher talent average and a win in the SEC. This year, those numbers dropped to to about 70% on a game-by-game basis.

We will begin with a look at how well the SEC fared over-all, and end with a specific discussion of UT and Coach Jones first year and a way-too-early look to the future.

THE SEC AT LARGE.

SEC predicted v. actual - Evaluations (2).jpg

Using four year talent averages as a guide, I have created this chart to show how those predictions did against reality. For every rectangle, the yellow highlighted team is the "subject". Any team below (lower talent averages) should be a win (green). Any team above (higher talent average) should be a loss (red). You can see that using these numbers to predict the seasonal outcomes resulted in 9 of 14 teams (64%) finishing within one game of talent predictions. 11 of 14 teams (79%) finished within two games of their predicted outcomes. Only three teams, Mizzou, Vandy and Florida, finished more than 2 games outside of talent predictions.

Missouri was the largest over-performer at +5 SEC games, and Florida is the largest under-performer at -5. This puts Pinkel at +5 for his career in the SEC, and Muschamp at -10 games. As a note, the threshold for firing is about -4 games below talent predictions in a single season.

Auburn, for all of the noise, finished EXACTLY as talent predicted. They lost to LSU whom they out-recruited, and beat Bama who they didn't. That is a wash, and they finished the season 7-1.

Talent predicts that the SEC championship game leans heavily in Auburn's favor (7.25 v. 34.75).

Before we begin this conversation, a brief discussion of Butch Jones is in order. Butch has never fallen below talent predictions as a coach before arriving at UT. In fact, over his whole career, Jones averages +3 games a year more than talent predicts (including his first year at UT). The key to reviewing Jones as a coach is seeing that Jones also improves talent in relation to his competition.

It took Jones two years at CMU before he won more games than his predecessor (8), and his first year at Cincy he won 8 games less than Kelly's last. Some cursory research into this phenomenon reveals that Kelly left a very depleted and angry roster at Cincy, and it took Jones a year for the full buy-in from a team that had experienced a 12 win season the year before.

His first year at CMU, Jones lost to NDSU by blow-out fashion (44-14 if memory serves) but still over-performed by 5 games. There are some intriguing losses on his resume (NDSU, Toledo, Uconn) but also some intriguing wins against teams who had recruited far superior talent (Michigan State, Pittsburgh, NCSU, Virginia Tech). It should be noted that while Jones is 1-1 against James Franklin at Vandy, he has had a superior roster both times.

Yes, Jones Cincy Bearcat team was Dooley's "signature" win. Dooley had a team averaging top 15 talent, and ran over a team who barely broke the top half of division 1 recruiting. That is neither a signature win, nor a signature loss, by either party.

Bottom line about Jones, his teams have won 10 games at least 50% of his career (if you count the 2012 bowl win against Duke that Jones did not coach as a win accredited to him). Overall, including this year, Jones averages 8 win seasons. Not too shabby when you see that talent predicted an average of 5 wins a year. If our talent continues to rise, imagine what an over-performance by 3 games a year would look like in the SEC.

2013

Talent predicted that Jones version of the Volunteers should go 7-5. Instead the Vols went 5-7 (it should be noted that Vegas thought the Vols would go 5-7). Jones spoke of razor thin margins: Team 117 missed the talent prediction mark by 7 points, give or take. Remember this was with a 4th string true-freshman QB coming in mid-season, against the pride of the SEC.

Much has been made about the attrition of UT being singular. I had looked into it, and found what I thought was proof that UT's attrition was well within the average ranges. I was wrong.

SEC east evaluations accounting for attrition.jpg

What I thought I saw there was a roster that when all attrition up to the spring game was added in, was unchanged in relationship to the other rosters in the SEC east. It wasn't until I saw the chart below, that I realized that I hadn't been looking close enough at how attrition, and walk-ons, had affected unit groupings on the field.

Book1b_Page_1.jpg

If you look at this chart, it compares the average star rating of every player on the two deep, including walk-ons, broken down by rough position groups. It then compares that with a rough approximation of what we can expect in 2014 with the incoming recruiting class replacing those projected to leave, and the lower rated or walk-on players. As you can see from this chart, Jones fielded a team that averaged (using Rivals data) a 5.11 player (or no star rating). The two deep had its bright spots, including the offensive backfield and defensive line. The weaknesses (given the two deep averages) were the secondary and receivers.

I haven't had the time, or the desire, to do this for all SEC teams to see if it drives the actual talent predictions downward. My gut tells me that it would probably explain the under-performance and make the win against SCAR look spectacular. At least that is what I hope I would find.

2014: too early to make predictions, but let's do it anyway.

Using a rough approximation of the incoming players, look at the jumps made in talent on the two deep that will see the field next season. Every position group beside defensive line and offensive backfield drastically improve. Linebackers go from averaging 3 to 4 stars, secondary goes from being not-ranked to averaging 3 stars, receivers go from being not-ranked on average, to averaging 4 stars. Overall, the average caliber of player on the two deep goes from not ranked, to 5 one hundredths of a point from averaging 4 star players. That is a drastic jump in raw talent, even if it comes in young.

The bright side? 14 of those players should enter as early enrollees, meaning they will get to participate in spring lifting, spring training, and all summer practices. That is huge for a young incoming class expecting to make drastic strides on the field.

Remember, Jones tends to over-perform by about 3 games a year, on average, but tends to appear stagnant, or worse, his first year on the job.

Stay tuned, I will do another talent prediction matrix after signing day, and we can then discuss how this incoming class should affect the seasonal predicted performance. For all of the nay-saying and hand-wringing, I see something very bright rising on the horizon...and it is orange.

EDIT: I left out what I believe is one of the most interesting comparisons of this whole evaluation.

Is 5-7 the same as 5-7?

Is Dooley's last season the same as Jones' first? The record would indicate so, but I think a deeper evaluation says no.

Dooley was a chronic under-performer, peaking at about 4 games a year. 4 games is the threshold delineating when a coach tends to get fired for under-performance (pay attention Florida fans). Worst case scenario, Jones under performed by two games in his inaugural year. That is an improvement over half from what we have seen the previous 3-4 years.

The following chart illustrates both Dooley's and Jones' talent predicted wins and losses over their tenure at UT. Notice how the talent predicted wins/losses trend about 2 games above Vegas predicted wins losses.

What this adds to my evaluation of Dooley is that not only did he find ways to not utilize talent, that our talent tended to drop in relation to our competition over his tenure.

i love stats n this-shows that cbj did underacheive based on the data but what this doesnt prove was why. what we have to ask, n only time will tell, has the level of competition gotten better n the sec vs. big east etc...so cbjs historical avg will trend down.

it will be interesting to see what the data shows his record should be in 2014.

btw i thought 6 n 6 reg season with a bowl win.

Interesting. I looked at the schedule at the beginning of the year, took a quick look at our roster, and predicted 6-6. Did I underperform by 1?

daj that is one of your best so far.

imo if UT had beaten UF and Vandy but lost to SCAR, the overall level of concern would be a lot less even though 6-6 is awfully close to 5-7. especially given that 6-6 would have meant a bowl game, extra practice including the EEs, etc.

maybe we look back in a few years and write off Vandy as one of those anomalies that just happens every now and then (like Memphis St in 96, or, uh-oh, SCAR in 13).

Great post. We did have two really close losses in Ga and Va. If those went the other way he would have been right on point with his talent. Also, I wonder how much our talent stagnated or even regressed under Dooley's leadership.

Isn't it refreshing to see someone put out theories that are actually backed by some substance instead of nebulous statements of somehow "knowing" the future?

If there were a way to statistically quantify the impact of having a first year starting QB who is then injured midseason and replaced by a true freshman QB then it might explain 5 wins instead of 7?

In hind sight, I believe CBJ under performed with a just a handfull of decisions and way over performed with changing the competitive culture of the team.

3 things that stick out to me;
- Should have stuck with Worley until he was injured. He pulled the plug too quick and it cost us a chance to win at FL.
- Too conservative of an O game plan with Vandy. Understand he thought his D could hold Vandy down and he didn't want his freshman QB to lose the game.
- The fake FG at Vandy was a poor decision.

I have read an analysis that suggests that changing from an experienced to an inexperienced QB accounts for .2 games a season. Yes, that is a two-tenths of a game decline that can be attributed to QB play. Most concerning is that the same analysis also said that going from an experienced to inexperienced kicker showed a decline of over 1 game a season.

I tend to agree with you. When wiping everything clean, and using an objective analysis to formulate my subjective opinion, I see improvements from what we had come to expect under Dooley. I don't know how to quantify it, but I am certain the culture change took a great deal of energy (think of the shift in APR, think of how some players have admitted that under Dooley they weren't even working out). Maybe Butch's meme of "process" really is true and not just silly slogans. Also, more often than not this year, I saw adjustments at halftime. When was the last time any of us saw that? I felt like watching this team that they had a Hunger that has been missing. Too bad the depth wasn't there. I believe it was Eisenhower who said "fatigue makes cowards of us all." I saw severe fatigue set in late season, most notably during Mizzou, Auburn.

I think too many are making too much out of the Bama, Mizzou, Auburn stretch of the season. I tried to caution everyone against assumptions about Auburn. That is a very talented team. Mizzou is one of the exceedingly rare cases where talent is coached way up. Couple that with some fortune (UGA being severely injured when they played, UF being injured and coached by a moron) and you end up with a team that wins many games. I caution Mizzou fans against feeling that this year is sustainable (just as aTm fans found out this year). I don't think it is until their talent level drastically improves. Bama is Bama. 90% of the time their exceptional talent and depth is overwhelming.

The win over SCAR was predicted by talent averages (perhaps not when looking at the position adjusted talent averages). Either way, I have tended to minimize the importance of that win. Spurrier is still a coach with a long historical ability of getting more from talent. He is tough to beat.

That leaves only one game that really frustrates me...Vandy. With 2 weeks to prepare, more talent and and home field advantage, I felt that game was a lock. A bowl game was on the line. That loss hurt. There are positives to take from that game, we held Vandy to below season averages. We forced a ton of turnovers against a pretty stingy Vandy offense. If it wasn't for a very unusual missed field goal early in the game, offensive play calling that went conservative only to be punctuated by a too aggressive fake FG attempt, I believe that outcome is different. I honestly don't believe you'll see another loss against Vandy for a long time.

Many of these evals and thoughts are "published" on my blog. Check it out (it's not hard to find if your blood is orange, like mine). I can't give a link or I get dinged by a mod as spamming. ;)

Yeah if i have a beef about this year it would be the gameplan against Vandy. It is what it is though. A lot of people thought 5-7 and think that's about where it will end up again next year. If we can continue to recruit well we won't have to play a perfect game and the coaches won't have to call a perfect game to beat a lot of teams. Vandy falls into that category.

I want to add one final thought and graphic for discussion.

I began this in another thread in the recruiting forum, but I think that it needs a more open debate.

The genesis of this is the idea that 6-6 is a threshold for a bowl game. That arbitrary record requires some assumption that all 6-6 teams are the same.

My conclusion after looking at the strong correlation between talent and victory is that comparing records against dissimilar teams is useless to determine who is better and that our current polling system is just as stupid.

For instance, if polls matter, shouldn't the higher ranked teams beat the lower ranked teams with consistency? If so, isn't it possible that the 8th best team in the land could have 7 losses (if they played the top 7 teams) and still actually be the 8th best team? Should they then, be denied a bowl and also be forced out of any poll? I would strongly suggest no, but that is what is wrong with our current system. And, that will not be undone by a playoff that ultimately takes the polls and gives them to a selection committee to decide the top 4 teams. Ultimately polls talk about respecting strength of schedule, but then will default to basically ranking teams by a win-loss record.

Using this seed of an idea, I wanted to try to create a ranking that begins with talent averages as a starting point. Remember, this is correct about 70% of the time. From there, adjustments are made at the end of the season not just by actual wins and losses, but by real upsets. In other words, a team should lose to a team with a higher talent average. That shouldn't count against them. Similarly, a team should win against teams with a lower talent average, and that shouldn't be seen as something worthy of moving up in the rankings. The end result should be a ranking, in my view, that allows for teams to only move up and down by true upsets, and not by accumulating wins against teams they should actually beat, or by losses to superior teams.

Here is my methodology. I start with ranking the SEC teams by raw talent averages. View this as a ladder with teams taking up sequential rungs. I then move over every team who won and lost as many games as talent predicted to the same rung (they were stagnant). Then, I take the teams who had an under-performance and move them down the number of rungs of their under-performance. Do the opposite for the over-performers, and then shove them all back together. If two teams end up on the same rung due to one's over-performance, and ones' under-performance, you would put the loser of the head to head match-up on the rung below the other. What you come up with is this:

Book1.jpg

I believe this more accurately displays the actual ability of the teams in the SEC based on starting point (talent) and ending with actual performance. I think that should this should be done for all division 1 teams that you would end up with a more accurate representation of the actual quality of a team instead of a poll that is a beauty contest (in fact driving teams to schedule crap OOC games for fear of a loss).

A ranking like this tends to mitigate one-game exceptions (Auburn/Bama; UGA/Vandy; etc) and simply allows for a closer "body of work" evaluation to be made. Look at Vandy, for instance. Vandy performed +3 games from talent averages, but still lost 5 games. If you look at their 3 wins, 2 of them came against teams under-performing and that tends to mitigate the rise of and quality of Vandy's overall "ability." That being the case, it certainly seems fair to allow Vandy to move up but to not take a huge jump like Mizzou, which is what exactly happened when ranking the teams this way. Thoughts?

wow - 2 pages on this post

I think you went over everyone's head with all this "smart stuff"

Try posting stuff like "Butch Jones is the SUXOR!!!!!!!!!!!" then maybe there would be more interest here...

you kind of lost me on that one. i'll have to study it.

I'm simply trying to find a way to erase the importance of scheduling, which penalized too much for a loss against better teams, and rewards too much for wins over lessor teams. The end result is a current polling system that ultimately creates rankings that are not supported by the predictive ability of recruiting adjusted for actual performance. I want teams to be ranked by those that are most likely to beat teams below them in a series of games. Ultimately we should wipe away subjective rankings and bumps for conference affiliation and end up with the top 70 teams going to bowls. 1 plays 2, 3 plays 4, 5 plays 6, etc.
