Running back is a notoriously tricky position to scout. The fact of the matter is that running backs come in all shapes and sizes, from (relatively) small scat-backs to massive power backs.
Somewhere in the middle are the generalists; runners who are good at a lot but don’t take any one aspect of their game to an extreme. They can have some measure of success in many situations, but they tend to not stand out as much as the blazing 4.2 speedster or the thundering power back.
Florida State runner Trey Benson is one of those generalists who’s good at almost everything, but falls just short of being exceptional in any one thing.
