Did Michigan State prove how weak the Big-10 really is?

It proves how bad Michigan State is and overrated they were, they had one good defensive player in Greg Jones, but look at the game scores, They almost lose to Purdue, they get thrashed by Iowa. I am not trying to be biased here at all but look at the defenses in the Big 10 and look how slow they are compared to SEC or PAC-10 they are slow, there is one defense that is probably the second quickest in the country behind TCU and thats Ohio State, if any of you have watched an Ohio State game just look at the swarming of the ball on every single play of the season, whereas Wisconsin had arguably one of the slowest Defensive Line in the country. The Big 10 is built on power, but if you have some speed like the SEC then you will be a high caliber team, just look at OSU. I will admit it im a Buckeye and the only reason they won some of those games was because of the defense, Pryor hasnt and probably wont develope into the QB everyone thought he was going to.
