As for your claim that the talent difference showed up in the 2nd half, I don't know that I agree with that assessment. Like the game changed so drastically with one big play in the first half in favor of the Gophers, that forced fumble was a good defensive play, sure, but the lucky bounce that put the ball right into a defensive players hands who happened to be facing towards the endzone with almost no one in his path to stop him from running it in for a TD had little to do with OSU's superior talent level. That was just a lucky bounce that went OSU's way. Had a Gopher been able to fall on the ball, I believe we would have had another shot to get a first down or we'd have at least gotten a chance to punt it away. Not saying the Gophers would have then won, but they may have been able to keep the final scoring margin closer. Not saying there isn't a talent difference, but I think that is more of a raw talent thing, as UMn, at least on offense, had pretty comparable offense.
That is part of the talent difference showing up. To win, Minnesota had to play a mistake free game. They pretty well did just that in the first half. In the 2nd half, they still didn't make a lot of mistakes, but the ones they did...cost them.
Basically, because of the difference in talent, tOSU had more of a margin for error than Minnesota did.
