At least in situational stuff, that is. He's light on his feet, & his length is much better than Lowell's. Of our 6'8+ guys, I see Haarms as likely our 2nd best perimeter defender — after Gavin. And I don't think there's a close 3rd, though maybe Lowell surprises me. I hope he can competently guard the SF spot, but I'm bit skeptical of that, too. I really haven't seen enough film of him, though.
