DB Juan Thornhill (2019)
40-yard dash: 4.42
Vertical jump: 44 inches
Broad jump: 141 inches
Thornhill was an absolute monster in the 2019 combine. His workout cemented Thornhill as a top safety in the class, showcasing immense physical tools. It was highlighted by an impressive 44-inch vertical jump that was one inch shy of breaking the combine record. The former basketball player wasn’t done there, though. He posted a long-jump that also tied the combine record for second-longest. He also ran a blazing fast 4.42 40-yard dash. It’s amazing that the Chiefs were able to grab Thornhill with pick No. 63 in the second round given his performance.
