Good call on Minnesota, and as you are a Big 10 insider you are on top of that.
Keep an eye on the freshman Charles Buggs. He blew up late and had offers from Marquette, Miami, Arkansas, Clemson, among many others, but Tubby nabbed him from Hargrave. He had 15 in the prep national title game vs. Brewster.
I tend to think IU is a little bit overrated due to their defense, but there is certainly a good argument for them at the top.
Baylor is the real sleeper to win it all imo. On paper the losses look like too much to overcome, but I think the balance and depth will allow the Bears to compete for a Final 4 and who knows once you get there.
