How is the roster any better? Everyone remembers Bonzi against the Spurs. Newsflash, he didn't play that well all season. In fact, as I recall, he missed a bunch of games in December and January (indeed, he played only 52 games all season). Kevin Martin is greatly improved. The difference for Rick from up till this point last year and the rest of the season was Peja for Artest. And we know what happened from there.
So, essentially, the roster is the same as it was at the end of the season. Bonzi-Kevin-Francisco becomes Kevin-Francisco-Quincy. Plus John Salmons. It's the same damn roster as the end of the last season, possibly better. And Adelman won like 2/3 of his games with this roster, while Muss has won 40%.
The Adelman haters are hilarious. Arguing that Rick would have done as bad? Hah. Arguing that Muss is going to be a better coach "in the long run" than "dam (sic) Rick Adelman"? You are delusional.
