Upon reflecting on the game, I actually think we played much better than previously under Pruitt. Sure, we had lots of penalties and heupel made a few bad decisions, but the scheme overall was very solid. With decent QB play we would have been up 28 points early on. Special teams played incredibly well. Defense played very well at key points in the game.
Bear in mind also that we were missing many key players in this game. The team never looked like they gave up, unlike during Pruitt's tenure where once we were down a TD or two you knew the game was over.
Of course a loss hurts, but there's a lot to be hopeful about. Also, typically coaches struggle in their first year. It's normally their 2nd year in which they get it figured out.
