TRB per hundred possessions:
Sabonis 22 (career 21. WOW.)
Simmons 18.5
Poeltl 18 (career 18)
Rabb 17
Ellenson 16 (surprsided so low)
Stone 14
Chriss 11.
Jared Sullinger 19, Olynyk 17 for comparison.
I like Sabonis more based on these stats. Amazing he can be so effective with such short arms and not a lot of bulk... he has unreal good hands. Meanwhile, Chriss is going to be a project at the NBA level. Not sure I'd take him in round 1.
