honestly, the only 2 bigs out there are Shittu and Hauser. Shittu has impressive ball handling skills. Hauser (if he has pro aspirations) would likely have to play the 3, but in college he could be stretch 4.
Bey is also not really a big, but there is talk he could grow some more. He could play some 4 like VJ did. He grew a lot in the last year and was a guard as a HS soph.
Finke is not looking for a college where he would play the 4. He is a 3/2. The only way that could change is if he grew a couple more inches. It's possible- his older brother is listed in the 6'8 to 6'9 range.
