1. Simmons - he will benefit greatly from NBA spacing. He can be dominant from the mid post even without a decent jumpshot, with the ability to punish double-teams with his awesome court vision. If he switches hands on his jumpshot and becomes solid, he has MVP potential.
2. Ingram - I love Ingram, but he isn't Durant. His mediocre FT% worries me, and he isn't that quick and explosive. However, he can be a pretty dominant shooter with his infinite length, and maybe he'll improve unexpectedly well with an NBA strength program.
3. Bender - I've waffled on Bender, but all the hate he's gotten on this forum has made me like him more. In the new NBA, versatile two-way bigs can make a superstar impact even if they only put up an efficient 15ppg.
4. Murray - here it gets really close. Murray is a really good shooter/scorer with enough size+athleticism to translate his game to the NBA, but I don't think he'll ever be a good defender. I do like that he can score equally well on and off the ball.
5. Dunn - he has really awesome tools and he's done a lot of good things in college, but he's somewhat old, possibly injury-prone, not a good decision maker for his age, and his shooting percentages might overstate his true shooting ability. Plenty of upside as a two-way PG, but plenty of question marks, too.
6. Brown - Freak athlete who can probably be a small-ball PF, but will he be a competent half-court scorer? He has two-way upside, but he also scares me.
7. Poeltl - I think he'll be a two way player in the NBA. Very good man defender, solid help defender. Good finisher under the rim, solid rebounder, sets good picks, does the dirty work. But he doesn't have the upside that some of these other guys do, on either end.
