The better question is "what's the biggest area for improvement other than QB play?" QB play is obviously #1 right now.
The run game is right up there IMO. It was not great last season. We had a couple of good games (e.g. Miss State) and then Eric Gray had a couple of monster games at the end (Vandy, Indiana), but we nevertheless had one of the weakest rushing attacks overall in the SEC. Gray has to continue to play like he did at the end of last season, the O-line needs to improve on run blocking, and we probably need a couple more RBs to step up their game.
Overall, we need the run game to take a major step forward this year, particularly given that we're losing Jauan Jennings and Marquez Calloway in the receiving game.
One thing that needs to improve is game management. There were too many times this year where UT screwed up end of half situations, didn’t know when to take timeouts, had to take timeouts coming out of a timeout. That’s inexcusable at this level and will come back to bite Pruitt in the ass if he doesn’t get it corrected.
Gotta go with all the components of the run game. Run blocking,right calls,timing with backs getting in the hole when it opens,etc. If that improves I think the offense will take the giant steps the defense did and hopefully continues to do.
Maybe not the biggest area of improvement we need to see but is anyone else tired of fair catches what seems like almost every kick for 2 years now? That's not Tennessee football. When was the last time somebody took it to the house? They need to step it up.
I think the OL play will be better at run blocking and even better at pass blocking. The improved running game will take pressure off of the passing game.
Of course we need better QB play and I think the OL will be a catalyst for that. QB battles in the Spring will be interesting to say the least. JG keeping the same OC for the first time in college will hopefully help but he has fundamentals and mechanics to work on too.
