Rumors of a Lee for Mayo exchange

Memphis has been a frequent caller on the trade market, and owner Michael Heisley is said to be adamant that the team make the playoffs, sources say. Some of the Grizzlies' focus remains on trying to move O.J. Mayo for a more traditional two-guard; some execs believe the Rockets' Courtney Lee would make sense, with the wild card being how highly Houston GM Daryl Morey regards Mayo. The Grizzlies have indicated that they don't want to give up Mayo without getting back a player who can help them down the stretch this season and an asset that can help them in the future.
