13. Robert Williams, PF/C, Texas A&M

Williams remains one of the top defensive prospects in a class highlighted by elite two-way bigs. At 6-9 with a 7-4 wingspan, his unique blend of mobility and athleticism allows him to alter shots in a variety of ways.

Like Bridges, Williams might have been better off declaring for the draft last season. He hasn’t expanded his range as a shooter and his offensive role has actually diminished. With that said, he’s the kind of difference-maker that’s hard to pass on towards the back end of the lottery.

Teams should value Williams’ rim protection and defensive potential enough to overlook some of his offensive flaws. If he can re-establish his jumper and begin to extend his range, that only improves his outlook long term.
