Maker seems too slim to play the 5. He'd have to play the 4 until he can add 20 - 25 lbs. He's raw offensively. I think his offensive development may end up being a process like Derrick Favors. He's pretty raw right now. However, if you want him, I think you have to take him at 12. Someone could trade up to take him at the end of the lottery.
I'd be interested to see how people rank the 8 - 10 bigs in the first round of this draft. I'd generally rank them like this ---
1 Simmons
2 Chriss
3 Poeltl
4 Ellenson
5 Bender
6 Davis
7 Sabonis
8 Labissiere
9 Maker
Damian Jones is a better prospect than Sabonis, Labissiere, and Maker.
