In his only season in Chicago, the 12-year veteran averaged 7.6 points and 6.7 assists per game, sometimes starting and playing large chunks of minutes, other times riding the bench. His stock was up with coach Fred Hoiberg as the playoffs began, but then he broke his thumb and the Bulls were swamped by the Celtics after taking a 2-0 series lead.
Chicago tried to trade him, but there were no takers. ESPN:
As it stands, the Bulls are on the hook for a $3 million guarantee still owed to Rondo. But they cleared more roster space for younger point guards Kris Dunn, Jerian Grant and Cameron Payne to get more minutes next season as the Bulls begin the rebuilding process after dealing All-Star swingman Jimmy Butler to the Minnesota Timberwolves on draft night.
My guess? Rondo is gone because Dwyane Wade didn't like him.
