In this case at least it's an actual comparison. I will agree with other people that THT has a higher upside, and he's definitely better a certain areas of the game than Weiskamp, Weiskamp is a really good player as well. I think he'll be an all-timer for the Hawks.

Sagarin has the Big 12 as better.
My point isn't to make an argument about that. Both conferences are very tough and any difference in the two is basically microscopic. There are basically three conferences that matter this year - The Big 10, the Big 12, and the ACC. After that it's just a smattering from other leagues.
SEC has improved a ton over the last few years. I would put them just a tier below those three.
