Sources say Blake, who averaged 7.3 points and 4.8 assists in 80 games last season with Portland and then with Clippers, is drawing the strongest interest from Orlando, New York and Toronto, with the Lakers and the Bobcats also being in the mix.
With that in mind, Blake, 30, is said to be able to command a contract around the $4.93 million he made last season, something that might not be possible if it were a stronger point-guard class.
While the Knicks are still waiting to see if they can get LeBron James, sources said the Raptors also are in a holding pattern. They have a pair of point guards in Jose Calderon and Jarrett Jack they're looking to trade.
Jack would be the preference to move since he was a disaster after being signed last summer primarily because he had played at Georgia Tech with Chris Bosh, whom the Raptors were trying to keep happy. But the Raptors certainly wouldn't complain about moving Calderon, who slumped badly last season.
If a sign-and-trade could be worked out for the departure of free-agent Bosh, the Raptors might look to try to have the team getting Bosh also take Calderon or Jack in the deal. Then Toronto would have more interest in signing a point guard such as Blake.
