Louisville freshman quarterback Lamar Jackson was, for an unknown reason, hanging out with Rajon Rondo on Monday. The two decided they needed to have a foot race in the street, and as you can see in the video above, Jackson put on the burners and left Rondo behind.
Here's photo evidence that it is indeed Rondo in the video.

Now, Rondo's 10 years Jackson's elder and has had some knee surgeries in the past, but he's still a top-level professional athlete so it shows that Jackson has some serious foot speed. We'll have to wait and see if that translates to the football field.
