Don't really see the Terrence Samuel - Craig Austrie comparison. Austrie shot the ball pretty well his entire career - always shot over 30% from three at least, which is okay. As we know, Terrence's stroke outside 15 feet needs an entire makeover.
I think Terrence Samuel is much more closer to a poor man's Taliek Brown. If we surround Terrence with 35-45% 3pt shooters and dependable posts that can shoot mid-range it'll eliminate his need to shoot. If he can create and distribute to these guys like Taliek did, he'll be a good player. More useful than Austrie at least.
