I like Clarke too, and I think if his 3-point shot holds up Memphis is going to be very happy with him. He has Rob Williams-level hops, but vastly superior instincts and timing, which help compensate for his arms, and throughout college he had an excellent midrange jump shot. If he becomes a good three point shooter he could be a very very good stretch four, possibly a wing in a long lineup. He makes a lot of sense on Memphis next to JJJ.
That said, who is the short guard who can’t shoot? Langford has shooting problems in college but he isn’t short; he has above average length for a 2-guard at 6’6” and 6’11”. His hand injury is well documented, so I’m not making a judgment on his shooting til he heals. Carsten Edwards was a college career 37% shooter on more than 7 attempts per game; in SL he was above 40% from 3, shooting every kind of 3 - off a screen, off the bounce, standing catch and shoot. We got Edwards by passing on Clarke.
