The defensive line is going to be an issue this season. We have no stars there right now. They are all just 'ok'. We clearly need a better pass rush, and our DTs get pushed around in the run game more than they should have against inferior opponents.
The RG is a problem. I have to think we have to have better long-term options there, but perhaps not with enough experience to replace our starter for another year. The TEs seems to be a work in progress (overall in a good way). Obviously Staes is a keeper, but the other guys appear somewhat limited passing options at the moment.
Our LB core is in transition. Liufau is good, the rest are 'meh'. We need better athleticism there. Can't wait for next year.
Hartman is really solid, but does hold the ball too long and will miss easy throws at times. Not sure if he has the arm for the NFL, but for college he is the perfect ND QB. I wish we had him for 4 years.
Estime is a beast, but we need to play the other RBs more as others have already said.
Our WRs are having a breakout party. Merriweather should have answered questions and quieted the board mini-meltdown over whether he can actually play. Flores will be productive for 4 years, and we have serious depth there. My biggest worry is next year whether Angeli can get the ball to them consistently, but when Minchey and CJ start I think we will have a very good passing game also with the younger TEs on the roster. This offense is going to be scary good in 2-3 years.
I am not sure we are at the level of OSU with current starters, across the board. I like our younger players better, and think we are serious NC contenders in 2 years. If we win this next game, it will be because of our young offensive skill players matching up well with their defensive talent. If we lose, it will be because the defensive front 7 simply wasn't good enough to contain them.
