Georgia running back Keith Marshall is putting on a show at the Scouting Combine.

Marshall, who impressed in the weight room yesterday with 25 reps in the 225-pound bench press, impressed on the field today with his 40-yard dash.

With an unofficial time of 4.29 seconds, Marshall became this year’s first player to break 4.3 seconds. Those in attendance in Indianapolis could be heard gasping, “Oooh,” as Marshall crossed the finish line.

That doesn’t necessarily mean Marshall will be a high pick. He only started two games at Georgia, spending most of his college career behind Todd Gurley and Nick Chubb on the depth chart. When he announced late last season that he was turning pro with a year of eligibility remaining, many thought it was a mistake.

But the 5-foot-11, 219-pound Marshall has shown that he has the measurables to play in the NFL. Scouts have to be impressed with what he’s doing in Indianapolis.
