Celtics point guard Rajon Rondo is listed at 6-feet-1-inches tall. He's not known as a high-flyer, but he's been known to throw down a dunk now and then (poor Chris Bosh) and is clearly blessed with incredible athleticism.
A pure glimpse of that athleticism is on display in the video above, taken at the Celtics' practice facility in Waltham. Rondo is coaxed to jump onto the box by what sounds like Celtics strength and conditioning coach Bryan Doo. After feeling it out, Rondo takes a step and hops right up. Pretty incredible.
