Okafor is molasses slow, lacks athleticism, doesn't rebound well, probably won't be a great P&R defender. Reminds me of a larger Al Jefferson with his refined post game.
From the limited time I've watched KY games, Towns doesn't seem to get much burn with all their talent - haven't seen enough to make any judgment. Think they'll take both some significant time to develop. WCS may actually be the earliest contributor in the league, but by far has the lowest upside.
