Pistons Guard Ish Smith Shakes Marcus Smart with Behind-the-Back Crossover

Marcus Smart wasn't ready for Ish Smith on Monday night. 

In the third quarter of the Boston Celtics' game against the Detroit Pistons, Smith drove toward the basket with Smart guarding him closely. 

Smith faked Smart to the left before making a quick shift to the right with a behind-the-back cross, then he shuffled over for the two-pointer. 

The whole thing happened a bit too quickly for Smart, who was thrown so off balance that he was unable to regain his footing, and briefly hit the ground. 

That embarrassment was short-lived, however, as the Celtics were ultimately able to edge out Detroit 113-109.
