As the 4th quarter was winding down and the Celtics were winning comfortably, JR Smith shoved Al Horford in the back as he left his feet on a drive to the basket. This caused Marcus Smart to react and come to the defense of his teammate which started a bit of a scuffle.
Clay Travis thinks that this move by JR Smith was a cheap shot and has no place in the game. Doing that to someone can cause serious injury and would likely spark a fight on almost any basketball court in the country. In fact, Clay wouldn't be upset if Smith was suspended for Game 3.
