Watching the UGA LSU game.... Todd Gurley is a monster, but has been banged up in both of UGA's big games. Behind him they have Marshall (very talented, but more of a change-of-pace back) and a freshman who looks like a fullback. Basically,when/if Gurley goes down, UGA has to fundamentally alter their attack. Mainly, throwing more on early downs and a much less effective running game.
We are SO fortunate to have the depth at such an important position.
