A veteran NBA agent believes that Dwyane Wade will be the hardest of next summer's unrestricted free agents to retain.

Wade, along with LeBron James and Chris Bosh, could all be unrestricted free agents after the 2009-10 season if they don't take their player options for the 2010-11 season.

"I think D-Wade will be the toughest to retain of the high-profile free agents," the agent told the South Florida Sun-Sentinel. "I just get the sense that he envies his buddy in Cleveland who has a better team around him."
