I haven't read a lot of ridiculous expectations on here or anywhere else for UT really. Sure you get the occasional record thrown out there from time to time, but I don't think that is the majority by any means. If you re getting worked up because fans think this team can win 7 or 8 games opposed to your 6 then it sounds like faux outrage.
The OL hasn't been good for years. Down right terrible most of that time. Its been that way due to development, talent, injuries and the changing of systems.
The fact our new OC (SEC veteran), is working a lot with them during fall camp is not a surprise at all. He is the 3rd OC in as many years for some of these players. They were terrible last year (everyone knows that) and that wasn't going to change without some change. It will become a bad thing if he's still heavily involved mid to late season and the product is no better.
The DL is the question on defense. The interesting part about that is most would agree we were pretty average there last year and a year later we are concerned about replacing average experience or players? The unknown creates a level of tension sure. But is it possible the DL is just as good (maybe better) this year with guys in year 2 of a better S&C and defensive system as opposed to guys only in it for a year. Less a rash of injuries they will be better behind them at LB and in the secondary. I don't think they will be an elite defense, but I will be surprised if they are not better than last year. And that's not an unrealistic expectation at all.
Getting "embarrassed" by BYU would be a problem, but on Aug 22 we have no idea if that is going to happen. If it does and there is not a solid rebound in other winnable games the rest of the schedule (State, Vandy, USC, UK, Mizzou) , yes you will struggle to finish with a good recruiting class.
To the 5 year plan. It may take him that long to win something of significance, yes. Where you can say "we re back" But you will see signs of that happening going forward. Its not gonna just all of a sudden happen. You should see a difference in this years team from last year. If you don't Id start to worry and question if he makes 5 seasons.
