CLEVELAND -- LeBron James' longest single tenure with a franchise is his current run with the Lakers. And his best seasons may have come during his four years with the Heat.

The door to a LeBron James reunion in Cleveland is not closed. In fact, it may be wide open. According to ESPN's Dave McMenamin, multiple team and league sources indicated that the Cleveland Cavaliers would "gladly welcome" James back if he chooses to leave the Los Angeles Lakers in free agency this summer.

It's possible Wednesday could be LeBron James' final game in Cleveland. The 41-year-old James hasn't decided whether he's going to retire after this season and his Lakers are about to play the Cavaliers at Rocket Arena for their only time this season.
