Shaquem Griffin just did something at the NFL scouting combine that no linebacker with two hands has done since results were first tracked in 2003: clock a 4.38-second 40-yard dash.

Griffin, the inspirational one-handed linebacker from Central Florida, wasn't even originally invited to the combine. Now he's put up 20 reps of 225 pounds on the bench press with a prostethic on his left arm — more than 11 offensive lineman — and broken the combine 40-yard dash mark among linebackers.

If Griffin still has doubters left, that's their problem. He turned heads at the Senior Bowl with his versatility, and his remarkable story just keeps getting more amazing. His twin brother, Seattle Seahawks' 2017 third-round CB Shaquill Griffin, clocked a 4.38 last spring... at 6-foot-0, 194 pounds. Shaquem Griffin measures 6-0 and 227 pounds and is tied with North Carolina State RB Nyheim Hines (5-foot-8, 198 pounds) for the third-fastest 40 time by any prospect through three days.
