Back to the OP - I agree. I have nothing but good things to say about Lawson. He got the current roster in shape and a lot of fat replaced with muscle in a relatively short period of time.
The problem has been they can't spin that they are going to make a silk purse out of a sow's ear when it comes to most of the upper classmen on this roster. What is even sadder it that those players trusted UT to provide what they needed to become good SEC quality players and did not receive it. So the issues originated from Kiffin, Dools, Hamilton, Hart (who had the opportunity to end it after the UK loss), Cheek, DiPietro, the BOT, and the big boosters. I hope a big time lesson was learned and is never repeated.
It will take all of this year going into next to reprogram the existing guys on the roster other than the 2013 recruiting class. So by 2015 we should see a totally different brand of football. At that point we should know if this staff is going to be able to get it done. Continuity, S&C, and the coaching staff getting better along with the players they coach will go a long way to making that happen.
