Execution, not play calling, make up the majority of issues on offense

I think the constant flip flopping of QB's plays a major issue too. I have no problem with Braxton running the wildcat, but Urban needs to pick a starter and live and die by him.
I worry about Tim Beck too. Our QB's seem to have regressed, which Nebraska fans always talked about Beck regressing Martinez.
The lack of execution from the oline is just killing us though. The play calls seem to be right when you break it down, but of course a good oline will make the worst play call seem right, and a bad oline will make the best playcall seem wrong.
