According to Chris Broussard from ESPN The Magazine, LeBron James told Ariza he would remain with the Cavaliers past 2010.
Even that wasn't enough to get Ariza, who verbally committed to join the Rockets last Thursday, to change his mind and go to Cleveland.
"Trevor asked LeBron if he would be in Cleveland after next season," the source said. "And LeBron said, 'I'll be there. Of course, I'll be there.'"
