After knocking down his free throw, Love grabbed a rebound on the defensive end and heaved a look outlet pass to a waiting James, who was bumped before dropping in his layup to put the Cavs up 80-78.
As James went to the line, Love walked over following his deep completion and slapped hands with Browns quarterback Johnny Manziel, who was sitting courtside.
Thompson was Cleveland’s best offensive weapon in the third, grabbing boards and scoring inside – once off a behind-the-back pass from James – to help the Cavs chip away at Oklahoma City’s 10-point lead.
Durant scored 14 points in the first quarter, but it was Westbrook’s basket that ended an 8-0 run to put the Thunder up by 12 early in the second quarter.
The Cavs, though, responded by ripping off 14 straight points in a three-minute stretch.
Westbrook seemed to ignore Dellavedova, who knocked down two 3-pointers as Cleveland went on an 18-0 run to take a 46-40 lead. Ibaka’s free throw ended Oklahoma City’s 5-minute dry spell and the Thunder closed the half with a 7-0 spurt to lead at the break.
