I'm not really feeling many upsets this year. I don't like any of the 12's, which I usually favor in picking my bracket. Maybe Chattanooga, but meh.
I actually like the 13 and 14's better. Got some good teams in there. I specifically like Hawaii. I think all the 13's and all the 14's except UB and UWGB are better than the 12's, outside of Little Rock. And I think Green Bay could be frisky enough with 2 star players. I just don't know about who will upset who though, as I do think the 3-5's are pretty strong with no glaring easy pickings. I'd say Cal, Iowa State and maybe Baylor are the most likely to blow their opener.
I think if Michigan and/or Wichita win their play-ins, they each have a great shot to get to the sweet 16. I don't think Northern Iowa and Gonzaga are as good as 11's, and face tough matchups.
