When I see DeMyron Martin run he reminds me of the old style I formation running back. Takes a while to get started but once he has acceleration he is hard to bring down.
Unfortunately he doesn't have that quick acceleration needed to the spread offense.
I saw play after play where he gets the ball in space but doesn't have the quickness to exploit it and gain positive yardage.
The spread needs a quick, smurf type running back. DeMyron is not it.
