WCS needs to learn the post up more than he does having a mid-range jumper.
A post up game will allow us to take advantage of whatever team decides to play small at the 4 position. Given today's trend, this should be perfect. Want to run a small-ball 4? Fine, we got WCS to guard him. But can that small-ball 4 really guard a 7'0 footer posting him up? Would that small-ball 4 rather have Cousins posting him up? Of course not.
Double teams all day.
