I think we'll be in the MNC mix next year. That doesn't mean we'll win it, but we'll be in the discussion. That's all you can really hope for each season. You never know when injuries, lucky bounces, and bad officiating will influence a game for or against NU.
For the offense, I think we'll have a top 25 offense next season. I know that sounds crazy, but we've got 10 starters returning. 10! With 3 quality RB's, all with some experience, and an improving OL, we should have the running game next season many were predicting us to have this year. Also, the WR's and TE's look pretty solid and could be special if Paul and McNeil excel and another WR and TE is at least solid. The QB position could be good, bad, or even ugly, but I think it'll be decent due to health, experience, and an improved OL.
For the defense, I don't think we'll be as dominating as this year, no matter what Bo says. But I still think we'll be top 10 or 15. That's still a really good defense. Losing Suh, Dillard, Asante, and O'Hanlon will definitely hurt. But our DB's look excellent and the DL should still be strong with Crick, Allen, and Meredith. The real question for me will be whether the LB's can emerge and play even close to how Dillard did. And how many running vs passing teams we'll face. Teams might find some success running, but passing teams could be in trouble against those corners.
