Cavs guard J.R. Smith had one of the dirtiest fouls of the entire playoffs when he pushed Al Horford in the back after he left his feet.  The foul sent Horford flying through the air and he landed hard under the basket.

Marcus Smart came to Horford’s defense and went after Smith.  But Smart wasn’t the only one who jumped in to defend him.

Horford’s sister, Anna Horford, dropped a “f*ck J.R.” tweet after the dirty foul. 

The Horford’s don’t play.  Maybe Smith should focus on scoring instead of dirty fouls.  He had more dirty fouls than point by failing to score a single point in 27 minutes.
