This trade may seem far-fetched, but I think it could work.
Lakers get: F/C Chris Bosh
Raptors get: F Lamar Odom, 2009 1st Round Pick
The contracts match up; Bosh is a free agent after 2010 and is making $16 million this year, while Odom is an expiring contract this year and makes $14.5 million. The pick allows Toronto to save some face (they could get Hansbrough at 29/30). The Raptors lose Odom's contract at the end of the season to go after a free agent (or two), while the Lakers get, well, Chris Bosh. I think it works for both sides.
