Each brings something different to the table and each has their own style out of the backfield.
What Marshall will bring is speed. He is an electric player in space and he is dangerous with the ball in his hands.
The 5-foot-11, 193 pound back out of Raleigh (NC) Millbrook changes direction with ease, he doesn't lose a step when he's not going north-south. He can be used in multiple ways at UGA, from running back to receiver to return man on special teams.
He has something UGA does not have on campus. Marshall has that speed and ability to make big plays from anywhere at any time.
Marshall will take that speed and that homerun threat, so what about Gurley?
The 6-foot-1, 210 pound running back out of Tarboro, N.C. will bring that downhill ability.
Gurley is a strong runner inside the tackles and he can get even better as he improves his pad level and his overall strength. He has the body that fits the SEC and Georgia's style of play.
He has surprising straight-ahead speed when he gets going and many to-be tackles slide off him when they try to arm tackle him. He is an instinctive runner and he just has a good feel for the game.
Marshall and Gurley attended high schools less than an hour apart in North Carolina and now they will be playing out of the same backfield in Athens, Ga.
Both know how to make plays, both will make each other better, both will benefit from playing with the other, and both could be used in the same backfield.
They are two backs, but Georgia needs them both. Isaiah Crowell was the top back in the country a year ago and he played well when he was healthy in 2011, but there was not a lot of depth there.
Marshall is the lightning and Gurley is the thunder, and this tandem hopes to help Georgia win SEC Championships in the coming years.
