Justin Darlington, a Canadian basketball player, is about to take flight.  Lightning fast with a 42.3" vertical, "Jus' Fly" is going to make your jaw literally drop after you watch this:

Yeah, that just happened.  If he has a 42" vertical while doing a cartwheel/round-off, I am legit shaking in my space boots at the thought of his leap at a full sprint.  At top speed, this guy could probably get his belly button over the rim.  It's way more electrifying than anything Blake Griffin has ever done and more exciting even than the historical 720 dunk from way back in the day.

It also helps that the guy is a world-class high jumper, which may help to explain his tremendous leaping abilities.  But the raw athleticism to land the cartwheel, grab the ball, go through the legs and finish the dunk is outright astouding.
