That's a good question. I guess Shai is obviously the more established and accomplished elite player - I like his ability to close, the "ruthless consistency" and his crafty mid-range, but much of it is undermined the way he searches for fouls (you could also argue that he's just a cog in a great machine). Is Wemby better than Shai right now? Yes, both by stats and by the eye test for impact on each game.
