As far as Ohio State having to defend against an opposing offensive player, is Wisconsin's Melvin Gordon (2,260 yards rushing, 8 y.p.c and 26 TDs) the best OSU has faced since their 2005 matchup against Texas's Vince Young?

if not who?

Tim Tebow was great, and hard to stop, but he wasn't at his peak when Florida played the Buckeyes.
