WATCH: LeBron James throws down massive reverse slam

LeBron James had it going in the first half of his Cleveland Cavaliers game against the Boston Celtics on Saturday.

In need of a win to make the Eastern Conference Finals an actual series after losing the first two games, King James dropped 19 points and dished out six assists in the first half en route to helping the Cavs to a 20-point halftime lead.

But nothing was more eye-opening than this reverse dunk by James in the second quarter.

First off, that was a beautiful backdoor cut by James. Heck, it was an even nicer pass from Kevin Love. Celtics forward Marcus Morris, much like was saw throughout the first half, didn’t have a clue as to what to do on defense.

Even at 33 years old, James proved he still has the hops and athleticism to throw down a raucous slam.
