If we get the pipeline rebuilt, the QB jabber will become all but nonexistent. Taylor Martinez would be remembered quite differently by most fans had he been behind a dominant OL. The QB just needs to be a game manager with few mistakes. We have more than capable QB's on the roster already. We just need better OL play.
I'm 100% behind you that we need better OL play, but, I would also argue QB is still huge no matter what. Nebraska hasn't had a truly elite QB since Eric Crouch I think you could argue. You could say TM got close but his turnover problems held him back, and there were times when even his freak athletic ability couldn't make up for the team's poor play. It's also tough to characterize someone as 'elite' when they were responsible for helping put the team into a deep hole.
Anyways, aside from Martinez, I would say we still need to have more than a game manager. OL play is definitely a big concern and I would love for them to be one of the best in the country, but a really good QB would mean a ton to this program and could mean the difference between getting to a conference title game and actually winning a conference title game.
