STRENGTHS - Marshall shows he has initial quickness when he gets the ball. He has solid footwork. Quick feet and can make quick cuts. Can get to the 2nd level quickly for blocking assignments. Has solid strength and has the ability to maintain his blocking assignment. Has good awareness and can pick up blocks accordingly. Can get to the outside quickly for screen passes.
WEAKNESSES - Marshall lacks explosiveness. While he shows the quickness when he is handed the ball, he does not explode much. He is not an elusive runner, nor does he show the ability to pound the football. He showed that while he is a good blocker when he does block, he is inconsistent in picking up blocks, especially in the 2nd level. When he is in the open field on a screen, he does not show the ability to break tackles, and lacks moves to make tacklers miss.
SUMMARY - Marshall has a solid frame and looks like a guy that should be able to pound the ball up the middle, however I just did not see that ability in any of the games I evaluated. He will get off the snap quickly and has the initial quickness once he gets the ball, but he does not show any explosiveness. It appears that he only has one speed and does not have the ability to "turn it up a notch." Marshall has very good footwork and has the ability to cut quickly to the inside or the outside, but he is not very elusive. He is not a guy that will break for a long run. He will block when he is asked to and he has the strength to block well, however he can be very inconsistent, at times completely missing a guy, especially in the 2nd level of the defense. He needs to be able to square up his blocks on LB's better and not run full fledge at them. While he can get to the outside well for screen plays, beyond that he does not show the ability to do much with the football after he catches. Overall, Marshall is a strong player that lacks elusiveness and power up the middle to be a starting running back and why he does not need to be drafted.
