I find all of the love for Miami to be interesting. Honestly, I think they're by far the worst 2 seed and was thrilled to have them in IU's bracket.
They won their conference tournament, which is all well and good, but the ACC is awful. Miami beat #90 Boston College, #35 NC State, and #28 UNC to win that tournament (Kenpom ratings). In fact, Miami only beat 2 teams in the top 25 of Kenpom all season (Duke and Michigan St, both at home). And in the meantime have 4 really bad lossed (Florida Gulf Coast, Indiana State, Wake Forest and Georgia Tech).
Miami is capable of a lot, no doubt. But, in my opinion they really benefited by playing in a terrible ACC, and having an awesome win against Duke. I have them into the Elite 8, but I don't see them having the players to run with IU.
Admittedly, I am extremely biased.
