J.R. Smith's major mistake during Game 1 of the 2018 NBA Finals on Thursday night (May 31) certainly cost the Cleveland Cavaliers a win. In last few seconds of the fourth quarter, the game was tied at 107 and Smith (who had possession of the ball) began dribbling it in the opposite direction after grabbing a rebound. "I was trying to get enough to bring it out to get a shot off," Smith told reporters after there was a belief that he thought the Cavs were a point ahead of the Golden State Warriors, who ended up winning Game 1, with a score of 124-114.
