Okay, so I've had great interest in how this conference realignment will change our schedule over the years and I've worked out some different scenarios using some hypothetical additions.
Let's say we add 4 schools to go to 16 teams. It seems unlikely that we'd keep a 8-team 2 division league which would result in terribly difficult scheduling. I think a 4-team, 4-pod system is the only way to go with 16 teams.
So, let's say we add ATM (done deal), Mizzou (likely), WVU (possible, but who knows), and ECU (possible, but unlikely). Due to the strengthening of the ACC and the $20 million buyout, snagging a team from that conference will now be very very difficult, though not necessarily impossible.
Now, let's say we move to 4 4-team pods.
North:
Tennessee
Kentucky
Vandy
WVU*
East:
Florida
Georgia
South Carolina
East Carolina*
South:
Bama
Auburn
Ole Miss
Miss St.
West:
LSU
Arkansas
A&M*
Mizzou*
______________________________
Now, with such a format we could have rotating pods which then comprise the 2 divisions each year.
So, one season it's North+South vs. East+West, the next rotation would be North+East vs. South+West, and then it would be North+West vs. South+East, and then back to the first year division format.
So, our schedule could look like this:
p=Pod rival, d=Division Rival r=permanent Rival/rotational rival
Vandy p
UK p
WVU p
Florida d
Georgia d
South Carolina d
ECU d
Bama r
So, in a season of North+East pods comprising a division, we could play our 3 pod-rivals, 4 division rivals, and 1 permanent rival in Bama each year, making SEC schedule 8 games.
Another season our schedule could be:
Vandy p
UK p
WVU p
Bama d
Auburn d
Ole Miss d
Miss St. d
Rotational Rival (Florida?) r
Now, whenever the North+South pods comprise a division, UT would play our permanent rival in Bama, making way for a second rotational rival game in years where perm rivals play one another. This rotational rival could be a single team, or perpetually rotated among different SEC team members. For instance, when North+South play one another, our rotational rival would be from either the East+West pods.
Now, let's look at the nitty-gritty of scheduling.
Let's say we move to such a format starting next year for hypothetical purposes.
With the pod-division format, we could have a 1-year or 2-year format (allowing for a contiguous home&home series). Thus, the North+South pods would be a division for two years before rotating.
In a 1-year format, where we would rotate pod-division lineups every year, a schedule with a particular team (let's say UF) would look like this:
2012: Home against UF
2015: Away against UF
2018: Home against UF
2021: Away against UF.
We would play a cross-pod team 4 times every 9 years, with a three-year gap in between each meeting. The gap between home games against against UF would be 6 years. So, in this format, we would see the Gators come to Knoxville every 6 years.
Now, let's change it to a two-year pod-division setup.
2012: Home against UF.
2013: Away against UF.
2018: Home against UF.
2019: Away against UF.
In such a format, we would play UF 4 times in only 7 years, but there would be a 5 year gap between the series and a 6 year gap between home games. Thus, we would see Florida come to Neyland every 6 years in this scheme also.
Now, let's take a look at how cross-division games are played in the current 12-team setup.
2011: @Arky & LSU
2010: @LSU & Ole Miss
2009: @Ole Miss & Auburn
2008: @Auburn & Miss St.
2007: @Miss St. & Arky
2006: @Arky & LSU
In the current format we play a non-permanent rival cross-division series with a particular team every 4 years. The gap between two home games against a particular team is 5 years.
For instance, the last time Arkansas came to Knoxville was in 2007. The next time they will be back is next season, 2012.
Thus, there is a 4 year gap between playing a team and a 5 year gap between 2 home games against a certain team.
Now, even with 4 new teams added, even with a 1-year or 2-year pod-division format, there are only 3 or 5 year gaps between games with a team and a 6 year gap between two home games against a particular team.
A 1-year pod-division format gives more frequent games than even the current setup, but only one more year difference between 2 home games. A 2-year setup makes the time between playing cross-pod/division opponents longer, but gives the benefit of back-to-back home&away series rather than spreading them out every 3 years.
The team with the best record of the pod-division is the champion and represents the division in the SEC championship game.
So, let's say this:
North+East division
North Pod
1. Tennessee
2. WVU
3. Vandy
4. Kentucky
East Pod
1. Florida
2. South Carolina
3. Georgia
4. East Carolina
Let's say Tennessee had the better SEC record between us and Florida, thus UT is the division rep in the SECCG from this pod-division.
The next season could look like this:
North+West Division
North Pod
1. Tennessee
2. Vandy
3. WVU
4. Kentucky
West Pod
1. LSU
2. A&M
3. Arkansas
4. Mizzou
Let's say that LSU has the better SEC record between us and them, so they would represent the division in the SECCG.
This is the only feasible setup I can see for a 16-team league. 8-team divisions would be so utterly cumbersome, both in scheduling and competition. You could never expect a lower-level team to compete in a 8-team division, but a 4-team pod helps the lower teams be more competitive, thus generating better football games and more intriguing match-ups.
This format helps maintain traditional rivalries, boost competition and spread it evenly, rotate cross-division games more fairly, and overall improve the quality of the football of the SEC.
You'll still see UT-Bama, Bama-AU, UF-UGA, UGA-AU, UF-LSU, LSU-Arky, LSU-TAMU, Ole Miss-Miss St., EVERY SINGLE YEAR. Little loss of traditional rivalries with the exception of Bama-LSU and UT-UF which could still take the place of the yearly rotational rival (seasons where UT's pod plays Bama's pod, our rival game is Florida, likewise LSU for the Tide).
