I know what the reports are saying, but I don't get why McDyess wouldn't want to play for the Nuggets.
He started his career in Denver, then the Nuggets traded him away. When he was a free agent he chose to sign again with Denver leaving a Phoenix team coming off 56 wins with Jason Kidd, Kevin Johnson, and Steve Nash all on the roster. Phoenix tried to re-sign McDyess and made a strong push for him too(from memory, could be mistaken though). Now if you're leaving a team with those 3 unselfish point guards to go back to Denver you got to figure the guy likes it in Denver (granted Nash and Johnson weren't back the next year but we're talking Kidd coming into his prime...)
Also Denver is a good team with a good core. They're coming off a 50 win season, have a still-getting-better All-Star in Anthony (whereas Detroit's stars are all on the decline) and have several solid players. As it is now, I say Denver still wins 50+ games this year and is in the playoffs, and I think they have about as good a chance to win it all in Denver as they do in Detroit.
I mean I could understand if the guy was traded to OKC, but I would figure he would like playing in Denver again.
