Agree with all the concerns. I also wonder how much the run defense had to change to account for a mobile QB.FGs are a legitimate concern. I think punting will be OK but not great.
Run defense is a legitimate concern against good teams. I think the problem is not just personnel but also a scheme that prioritizes explosive plays over plugging gaps.
Illinois OL might be stronger than PSU's DL but I don't think their offense can score as many points as PSU's offense.
