Nobody is underestimating Scharnowski here, I stated he's a guy who averaged 10 & 6 in the Horizon league. That isn't even an opinion, but merely a citation of his production and at what level.
Arizona's frontcourt is not better if you think it's just Krivas and Holmes. They have Kharchenkov and Godfrey as well. That's 2 players returning from a F4 team and another player coming from a 24-11 tournament team in which he was their best player and leading scorer. That is a wealth of tested depth in comparison to Duke.
