It’s early at the Senior Bowl and a buzz is already picking up on Donnel Pumphrey. Don’t be surprised when the Darren Sproles comparisons start. This young man is very short and light for a running back but he makes up for it with speed, quickness and agility. In fact he’s now the all-time NCAA rushing leader. Every time the football gets in his hands, he does something positive with it. Maybe not a pure three-down back, but a dangerous offensive weapon.. RB. San Diego State. Donnel Pumphrey . 5. player. 30
