Good points Derek. Way to pounce on me with both feet bro.
I never said that the "reason" the big ten is overrated is because they're mediocre and beating up on each other. Clearly, that is not WHY KenPom's numbers are skewed. I would have a couple theories regarding why their numbers are inflated.
#1 The initial ratings for some of their teams were skewed. Mich St is a likely culprit. They were highly rated from the beginning. They have remained highly rated despite their mounting losses. Ohio St is another example. (UK didn't help their over-rating, either)
#2 The ACC-BIG10 Challenge brought the ACC's early ratings into play as well. This was one of the few years the Big10 won that challenge. It was assumed at the time that the reason they won it was because of how dominant the B1G is this season. We've since learned that it was because the ACC is terrible this year.
Those are a couple theories. Attack away bro. Since the conference teams became overrated, they've since just beat up on each other.
I can't fully explain how the ratings got screwed up, obviously, but it's clear they're skewed. Wouldn't you agree? Or do you think all 12 of their teams are among the top 36 nationally?
