As bad as our offense has been, it seems we are playing better than last year. If I read your graph correcly, we were shut out 3 times last year. In addition, we scored defensive TD's against TCU and Texas. Otherwise, we'd have another shut out and the schedule was not nearly what it has been this year.
I think DC is still trying to get the players he needs to run his offense and some of the players he's recruited to help (mainly some JC guys) haven't panned out yet. But, the easiest part of our schedule is ahead of us. Hopefully the speed of the top ranked defenses will help us going forward. And, maybe we can open the play book up a little.
