I understand the desire to go big, and we might end up needing to do so against big teams like Gonzaga.
If I were to go big, though, I'd probably go with Austin, Kaufusi, Davis, Chatman, and KC. I don't think Aytes has the mid-range to 3-point jumper, or the handles to play the three.
Here's the exciting thing about future rosters. We'll have some really good sized guys that can legitimately shoot the rock...guys like Hartsock, Seljass, and Dastrup could legitimately play the 3, maybe even the 2 and be effective. A lineup of Chatman (6' 5"), Hartsock the younger (6' 8"), Dastrup (6' 10), Mika (6' 10"), and Kaufusi (6' 10") has the potential to be a really skilled and really physical lineup.
