VIDEO: J.R. Smith throws down insane 2-handed reverse oop

Cleveland Cavaliers shooting guard J.R. Smith was on a mission Sunday.

As part of an easy 101-82 victory over the New York Knicks, Smith threw down a pair of highlight dunks against his former squad.

The first dunk was a double-pump slam, and Smith later topped it with this ridiculous reverse alley-oop.

Smith finished with 17 points on 7-of-11 shooting and was a plus-26.
