Raptors forward Chris Bosh doesn't want to be thought of as an afterthought in the free agent sweepstakes this summer. "I don't want to be mentioned as an addition to a team," Bosh said prior to the season. "I want to be mentioned as the guy that people want to center their team around." Bosh hasn't changed that stance, saying recently that he's decided to distance himself from fellow free-agents-to-be such as LeBron James. He is often mentioned as the third-best option on the market behind James and Miami's Dwyane Wade. Toronto general manager Bryan Colangelo has admitted that he's open to a sign-and-trade involving Bosh if a new contract can be worked out. "I'm not an addition. I'm a centerpiece," he said. "I have to have that confidence in myself, and I want people to know that, because I'm not somebody that helps out. I'm the guy you get like, 'Yo, we're going to win a championship, you're gonna take us there.' "I want to hold onto that because I think every kid when they dream about playing basketball, they don't dream about being a role player. They dream about being the man. I have that position in Toronto and to give that up and go somewhere else to be an addition would kinda defeat the purpose of my dreams." http://www.nba.com/2010/news/features/art_garcia/06/20/chris.bosh/index.html
Most dream about winning championships, amirite? Bosh dreams about being Joe Johnson in Atlanta, not Joe Johnson in Phoenix.
Bosh could do it, but he would need to have what Boston had in their championship run. Pierce, Garnett, and Allen pretty much had equal status on that team and none of them could outright say they were "the guy" or who was a support guy. If he's happy with that then he could do it. If it's Bosh plus some random assortment of role players, well, he's already shown he can't lead a team like that to anywhere promising.
