And his time in the 40-yard dash (4.8 seconds) is unheard of for a guy who weighs 275.

His client list includes Andrew Luck, Marshawn Lynch, Reggie Bush and Le Sean Mc Coy.

Still, after just one session with Shawn Oakman, high-profile trainer Travelle Gaines didn't hesitate to make a bold assessment.

"He's the most genetically gifted athlete I've ever seen with my own eyes," Gaines says. He shocked me with some of the things he can do." Oakman spent two weeks this summer training at Gaines' facility in Las Vegas.

Gaines says he won't be shocked if Oakman is the No. Teams haven't been shy about taking defensive linemen high in the draft in recent years. "In 2012 people said Andrew Luck was the best pro prospect to ever come through the NFL combine," Gaines says.

Houston took South Carolina's Jadeveon Clowney with the No. "But this spring I won't be surprised if Shawn has the best combine of anyone in history." Such praise doesn't surprise coaches at Baylor, where Oakman has continued to one-up himself in the weight room since his arrival in 2012.

This summer Oakman did four pull-ups with a 120-pound harness attached to his body.His bench-press (400 pounds) and squat (600) numbers are even more impressive considering the length of his arms and legs.The highlight of his workouts came when Oakman jumped onto a 40-inch box—while holding 70-pound dumbbells in each hand.A video of the feat has been viewed more than 110,000 times on one You Tube video and 50,000 times on another.The way Gaines sees it, Oakman didn't cost himself money by opting not to enter last season's NFL draft.If anything, the decision will likely make him richer. Athletically, Oakman is expected to test better than both players.
