What have learned over the last few weeks is that you need a good experienced QB to win big games. The vikings, gophers and buckeyes all got beat by the team with more experience and overrall greater ability. Teams need good QBs.

They also need lines to give them time. Some of those teams you mentioned had good ones, others don't.
