Keon Johnson broke a record older than he is at the 2021 NBA Draft Combine.
The 19-year-old Tennessee product recorded a running vertical jump of 48 inches, per Kelly Iko of The Athletic. That broke the combine record previously held by Kansas’ Kenny Gregory, who jumped 45.5 inches in 2001.
Here’s his jump, via the NBA Draft’s official Twitter account.
Johnson also recorded a standing vertical jump of 41.5 inches.
Johnson’s athletic prowess is not a surprise. The 6-5 guard showed off big-time hops during his one-year college career. A clip of a dunk against Georgia made the social media rounds Wednesday night after Johnson’s vertical numbers were confirmed.
The play certainly demonstrates how his jumping ability can be used in-game.
The athletic testing numbers should only help keep Johnson’s stock rising. He is projected to be a top-10 pick in Stock Market Pioneer’ latest 2021 NBA Mock Draft.
NBA DRAFT BIG BOARD: Ranking the top 60 prospects in 2021
Johnson is not the only 2021 prospect to crack the list of top five jumps of all time. Texas center Jericho Sims (6-10) posted a 44.5-inch running vertical jump, tied for the third-highest with Pistons guard Hamidou Diallo.
Several other recognizable names are among the top 10 verticals in NBA Draft Combine history, per ESPN’s Jonathan Givony. Only one of them was listed as smaller than 6-0 (Kay Felder, 5-9).
