That is Utah’s 2nd round pick (#52) Joel Bolomboy showing off his hops. The 6’9 Ukrainian was the Big Sky Player of the Year and Defensive Player of the Year last year at Weber State.
He also played and struggled early on during the NBA summer league in Vegas but finished strong with 20 points (9 of 12 shooting), 7 boards, 1 steal, 1 block and 1 3 in a 92-88 win over the Lakers.
Back to those hops of his, look how explosive he was in college.
My bad (the dunk was too good not to share), here’s a video showcasing how explosive the potential 2nd round steal was in college.
