He's also quite a bit bigger than Fab. IMO, he looks better than anyone the Spurs have had playing next to Duncan since Dave. He appears to be a mobile big man with good size and very good basketball IQ. Offensively, he's not going to be a goto scorer but he can catch and finish off the pick and roll and that's huge.
I think he's going to be a very nice addition. They're still not going to beat the Lakers but nobody is.
