Yeah, if you're a Pistons fan McDyess is the one that you ought to be sad to see go. Iverson will be an improvement at point guard over Billups. They're both very talented veterans but AI is just better at creating his own shots and he's also still a very solid defender at this late juncture of his career.
McDyess is a very efficient, high energy player who rebounds very very well, especially when he's pounding the offensive glass. I think he should automatically start over K-Mart in Denver and he'll be a force for years to come.
