My picks:
Coach-Byron Scott. Plenty of people were picking the Hornets as DOA at the start of the season. Instead they managed to stay in the hunt for a playoff spot in the most difficult division in the league. (AJ gets my second place. He's gotten a marked defensive improvement out of guys who haven't played much of it before.) AHF is right. D'Antoni sucks.
MVP-Nash. Without him the Suns are a lottery team. It seems unfair to give it to a guy who has ty D, but he's spent the majority of his career playing under coaches that thought defense was a dirty word.
DPOY-Bruce. To be perfectly honest I think both he and Big Ben are perfectly deserving. Bruce gets the edge because he hasn't won it before (and he plays for the team I like.)
Rookie-Chris Paul. Duh.
Most Improved-Tony Parker. Boris Diaw seems the most concensus pick, but so much of his improvement has to do with his change in scenery. He went from arguably the worst organization in the league to playing in a system that he fit into much better, and playing twice as many minutes (in part due to front court injuries.) Meanwhile Parker has added the two things that Spurs fans have been clamoring for since he got to SA: a jumper and consistency from week to week. I'll readily admit this is a bit of a homerish pick, but I honestly believe Parker's name needs to be in the discussion for this award more than it has been.
Sixth-man: I dunno? Stack? This is one award that I'm always terrible at picking because I just don't follow the league in general well enough to pick up on this.
