San Francisco 49ers tight end Vernon Davis also made our previous list of fittest NFL players, and for good reason. The 6'3", 250-pound bruiser is arguably the fittest tight end in the league today. Not only has his ever-increasing production at the position helped the 49ers remain of the NFL's elite teams, but the guy is also just an absolute genetic freak. He posts a blazing 4.38 seconds time in the 40, has a vertical leap of 42 inches, bench presses more than 450 pounds, power cleans 365, and can squat nearly 700 pounds. Yes, you heard that right—700 pounds. Davis’ unstoppable exercise routine and superlean diet helps him maintain his freak-of-nature size and strength, but it’s the tight end’s dedication and heart that makes him a standout on the field of play.
