Cousins is a center! I've watched this kid play for quite a while, and if you want to develop him where he'll be able to use all his abilities, the you plant him near the basket where he can score and rebound. Put him at PF and you have him playing away from the basket guarding guys like Milsap, West, Landry etc. All guys that are quicker than him. You want a shotblocker, then draft or trade for a player that can play PF and still block shots. There are two guys in the upcoming draft that fit that bill. Davis and Drummond! Not saying we'll be able to draft either, but thats the type of player we need next to Cousins.
As far as our biggest need right now. A SF that can play defense, handle and pass the ball, and spot up well enough to where you have to guard him.
