I don't think it'll happen, too many teams are gunning for Wade in 2010 for him to choose Canada. Not to mention I think Wade is probably 80% likely to just stay in Miami, Lebron is the guy that's probably moving to NY, Chicago, or Brookyln if they move in time. Chicago is the team I'd be most scared of, assuming they move Hinrich for expirings they should have the room for sure, the allure of "Here's 25 mil a year to come play with Derrick Rose in MJ land" would probably be hard to turn down.
Joe Johnson is the guy I'm looking at. Caldy, Johnson, Bosh, and Bargs... fuck yeah!
