There's no denying that OSU had a talent drop off during the end of Tressel's tenure as an entire club. As soon as Urban got here, that's one of the first things he said after getting to practice with the team. The LB, WR and OL were all pretty bad in terms of elite talent.
I get it, Tress won (A LOT). I'm just saying if he coached another 10 years at OSU, the lack of adapting in terms of getting elite talent would have absolutely caught up to him.
