A Celtics fan showed off the ugly side of sports after Russell Westbrook led the Rockets to an overtime win on Saturday.  He led Houston to the 111-110 win over Boston with 41 points.

The Celtics fan responded to Westbrook’s big game by DMing his wife.  The fan trashed Westbrook before wishing cancer on their family.
