I think that Limegrover did a horrible job against Iowa and a pretty bad job against Michigan. I do still believe that he was a big part of the problem for those two losses. At the same time, on our four game win streak, his creativity and better playcalling was a big part of what was right for those wins.
Having said that, I have no beef with him after yesterday. He was dialing up plays which left receivers open enough that a college QB should be able to hit them. I like Nelson. I think he is a good quarterback and a good kid. I'm excited to see what he does against MSU and in the bowl game, and in the next two seasons. Unfortunately, he played terribly yesterday underthrowing some balls that could have been plays and that fourth down miss to Dos Equis was absolutely inexcusable. When he did make throws, the receivers did him no favors by dropping the ball. Against some defenses, when our QB and receivers are playing like that, we can just get more run heavy. Wisconsin is a good enough defense that a team with our skill level can't just pick and choose how we beat them, we need to take what they give us. Yesterday, they gave us the pass game, we had plays called which would have worked if properly executed, and the kids didn't make the plays.
Long story short: I think you can fairly argue that Limegrover was (at least partly) what cost us the Iowa and Michigan games, but there is no way this loss is on Limegrover.
