Tough call. I'll go with this year's win over OSU in Stillwater slightly over this year's home win against Texas just because it was on the road.
Remember, that was the game where the ice storm hit and OSU gave free admission to the students, who packed the place and were feeling the upset. Then we just came out and dropped a jackhammer on them.
Blake was dominant, AJ was throwing daggers, Pattillo was a manchild that game, and the OSU fans went home disappointed again after losing their national title game at home.
