Phoenix changed things up starting Diaw in place of Hill, and I'm not sure the Spurs can match up with 3x 7-footers (or partial 7-footers).
I don't know why D'Antoni waited until they were 3-0 to make the adjustment. It's quite obvious that Parker does NOT play well when someone with length is defending him, or providing help defense. This is why the Suns matched up so well with the Spurs last year, namely because Marion was able to shut Parker down at times. Anyone that is taller and athletic will bother Parker, and I'm very surprised D'Antoni waited this long to make the switch. As much as everyone likes Grant Hill (he is a great guy) he really is struggling right now with the injury and should have sat from the start.
Still, it's good to see the Suns win one and at least prevent the sweep. Can't see them coming back from here though. History is against them.
