this is big news
The Lakers also are expected to enter the picture with a bid for Bosh as it became clear in the Finals they need more scoring. And you can be sure they don't want to see a LeBron/Bosh pairing in Chicago with Rose and Noah to go against. The Raptors would like to get something in a sign-and-trade for Bosh, but they likely won't deal him in the East. The Lakers are expected to offer Andrew Bynum, a legitimate low post center, and Lamar Odom, and take back Jarrett Jack, whom the Raptors would like to move.
Then the Raptors move Andrea Bargnani to power forward and they have a good nucleus. Bosh wouldn't have to play center with Pau Gasol in L.A. A big issue with Bosh is not playing center, which he might have to do in Miami or New York. Remember, once you sign your leverage is gone. So Bosh isn't rushing to teams with no center."
