Following up on his 25-rep performance on the bench press Thursday, the Georgia running back turned heads on Friday with a blazing 4.31-second 40-yard dash. It was the 11th-fastest 40 time run at the combine since numbers first started being tracked at the event in 2003. Chris Johnson's 4.24 is the fastest.
In three seasons at Georgia, Marshall rushed for 1,379 yards and 12 touchdowns. That's a season for a lot of the top backs in college football. But Marshall, a highly touted five-star recruit who entered Georgia in the same class as Todd Gurley, suffered multiple knee injuries. He tore the ACL in his right knee that essentially forced him to miss major portions of the 2013 and 2014 seasons.
Which only makes his performance this week at the combine even more remarkable.
On Wednesday, Marshall went through an "intense" medical process with NFL team doctors who "pulled on you a lot," Marshall said. He reported that "medicals went great."
"All the teams, I didn't have any re-checks or anything like that. The doctors said (my knee) looks as good as it can, so I'm excited about that. I knew that coming in, but I'm excited I got cleared and all that and I'm ready to go."
Was he ever. On Friday, he put on a show that most certainly cleared up any questions teams might have had remaining about his right knee.
