Shaquem Griffin steals show with bench press at NFL combine

The inspirational story of Shaquem Griffin has been so extensively chronicled, one might presume everyone on the football landscape realizes he's a beast on the bench press, one hand and all.

Evidently, one NFL general manager didn't get the memo.

When a reporter at the NFL Scouting Combine informed Griffin that a GM — who admires the former UCF standout — would be content to see him do five reps of 225 pounds on the bench press, the Lakewood High alumnus responded by doing four times as many.

Don't believe it? Here's the clip.

"People didn't think I'd be able to do it, and him just saying five (reps), I mean, five to me is just warming up," said Griffin, who used a black prosthetic device affixed to his left forearm. "So it felt good to throw up 20 and show I can do way more than five."

Griffin, generally projected as a Day Three draft pick, measured in at 6-foot-1, 227 pounds at the Combine. He recently penned this open letter to NFL executives, sharing a bit of his backstory and candidly discussing how doubt motivates him.
