The way to beat UNC is to make your 3s. I don't think Wisconsin and Oregon can make enough 3s to get it done... though the return of Dillon Brooks for Oregon could make it interesting.
Louisville vs. Baylor in the title game imo... and Baylor could get it done. Strong point guard play, enough size to deal with Louisville inside, and Louisville is a terrible free throw shooting team.
Iowa State-Miami should be a really good one... and the winner to play Gonzaga. I like Gonzaga to beat either, though Miami in particular could be a tough matchup for them.
Dayton doesn't have the size to deal with UCLA's bigger bodies... and though I think Texas A&M easily has the talent to deal with UCLA, and they're much better defensively than UCLA, it's tough to imagine A&M winning in what is basically a home game for the Bruins, all things considered. Gilder will have to really shackle Lonzo Ball for A&M to get it done.
