CB4 interview with InsideHoops. My biggest worry is that if he doesn't start winning that he will bolt for another team when his contract is up. He still talks about winning now, however mentions how the Raps are building around him. I wouldn't think you'd talk about that if you were leading towards leaving. Source
Just to add to that.... here's another Bosh interview done by Hoopsworld http://www.hoopsworld.com/article_14363.shtml
Its good to see that Bosh looks forward to building chemistry with the guys, and doesn't count his team out regardless of any circumstance. Gotta love his character.
