What? The exact opposite is true. Over the long haul, Antonio has no where near the upside as Blair. If these early season games are just the throwaways Pop is treating them as then he shouldn't be playing Antonio very much and he should be playing Blair.
McDyess is a known commodity who isn't going to get much better. Blair on the other hand is likely to get much better and be a of a contributor. He woudln't be the first undersized power power forward to help the Spurs to a le. Malik Rose anyone?
