Danny Green did just fine in that offense, tbh.He's actually terrible attacking close-outs. If he gets a straight-line to the hoop, then he's great. He can get over defenders. If he has to do moves of any more complexity, it's (so far) a lost cause. There's a reason he has around a .500 assist/turnover ratio. He doesn't see anything when he has to make these moves, doesn't see help defenders, doesn't see his outlets.
He really is a guy you stick in the corner and he's great at relocating along the perimeter. He's good at cutting. But he's going to be a mess in the Spurs' motion offense, which is trying to get back to the beautiful game. He can't do that stuff. Maybe down the line, but there's not much rudimentary ability at this point. Maybe he works if you're just going to run the equivalent of 4 down for Wemby over and over where everyone's just watching him do his stuff and kicks out if he's in trouble.
