Dylan Perrenoud is a 6’4” dunker who jumps off two feet with a left-right plant and a listed vertical of 42 inches. His signature is a 360 behind-the-back.
At 6’4” with a 42 inch vertical he sits in the range where the reach is comfortable and the difficulty is all in what happens on the way up. The 360 behind-the-back tests that directly: the spin has to be started early enough to be finished square to the rim, and the ball has to be swung around the back and recovered while the body is still turning. It is the harder of the two ways to get the ball around the body, since behind-the-back gives you no view of the ball at the handoff point and no leg to bounce the timing off.
His footage comes out of the Utah scene, filmed in gym sessions rather than at contests. That is where most of the dunkers in his bracket are right now, since the contest calendar in the United States thinned out after the Sprite Showdown era and has only recently started to rebuild around the Dunkman League and the 3x3 circuit.
There is no published contest record on him. Rather than fill the gap, this page stays with what the footage and the measurements support.
