I think Sloan should be in the discussion every year that the Jazz make the playoffs; it's a traveshamockery that he's never won it.
McMillan, any other year, would have won it for the way the Blazers soldiered on through the injuries, but honestly, even though they had a ton of them, their main guys (Roy, Aldridge, Miller, and now, Camby) were on the floor almost all of the season. I guess Roy missed about a month, and that's rough, but most of the injuries were to roleplayers that were/are replaceable. I think the trade for Camby was a bigger impetus than anything else for them getting into the playoffs. But he's definitely deserving of consideration, no doubt.
As for Brooks, you go from 23-59 to 50-32 in one year, in the Western conference, and you have one of the youngest teams in the NBA? I think that's enough right there. It's just so radical and unheard of to see that kind of turnaround in one season, period, without adding a superstar/s, to take essentially the same team you had the previous season and make them almost thirty games better, in the TOUGH Western conference. The last time I remember a turnaround like that was Boston, and they added two superstars. Before that, it was the Suns adding Steve Nash, who won MVP two years in a row, and before that, it was the Nets adding Jason Kidd in his absolute prime, and was MVP runner up. To see such an improvement essentially come from within (they added three bench players, all rookies) speaks volumes about the coach. Not underestimating the improvements from legitimate studs on the team, because Durant and Westbrook are gonna bring a reckoning to the West for the next several seasons, but I think Brooks is incredibly deserving, more so than McMillan and Sloan.
