Ojeleye has priceless reaction to Time Lord's dunk in C's-Pelicans originally appeared on NBC Sports Boston

Robert Williams' insane athleticism got a rise out of one of the Boston Celtics' more stoic players Sunday.

In the first quarter of the Celtics' game against the Pelicans in New Orleans, Jaylen Brown found Williams for a thunderous alley-oop over Brandon Ingram.

Watch the highlight-reel play in the video above -- and keep an eye on C's wing Semi Ojeleye as Williams elevates for the slam.

We can't believe it either, Semi.

Williams always has had ridiculous hops, but the third-year center is starting to play more consistently on both ends of the floor. He also swatted Brandon Ingram in the first half Sunday and had four points, five rebounds and two blocks in the first half alone.

We have a feeling this won't be the last time that Time Lord leaves his teammates in awe.
