Considering the jump in the first year in the ranking with the athletes from the 07 team. I would say it's schemes but more importantly it's the coaching. Pelini has brought in better athletes as well. In 09 Pelini red shirted 15+ freshman defensive players. The defense you see today is the result of the 3rd year in the system and the influx of the redshirts with that extra year of coaching.
Bummer. I was hoping you guys would hire another turd for a coach.
Then again, Callahan recruited pretty well, so I was expecting whoever followed him to have early success.
I'm going to miss hating on the 'skers after this season. Sure, I could do it from a distance, but without the annual matchup it just won't be the same.
