JR Smith exchanges words with Heat players, guided off the court by Lue and security

After the Cavs loss to the Heat, JR Smith and Rodney McGruder took part in a heated exchange, as Smith appears to have taken offense to McGruder’s slapping Frye.

Per ESPN, Cavaliers guard J.R. Smith was guided off the court by Cleveland coach Tyronn Lue and members of the team's security staff at the conclusion of their 120-92 loss to the Heat on Saturday night, after he engaged in a shouting match with several Miami players.
Several Cavs security guards came to Smith's side and appeared to calm the 13-year guard until the final buzzer sounded. Former Cleveland guard Dion Waiters approached the Cavs bench while yelling and pointing in Smith's direction.
