I've been thinking about this one lately. I think having Foster as a #2 back to take some pressure off Gurley would be great. Sure, Foster isn't what he used to be but he's still got great vision and would be much better than most backup running backs. He would likely stay healthier now that he wouldn't be the workhorse and he's versatile out of the backfield. Gurley, Foster, and Mason/Benny would be a very solid trio of backs. If they can get Arian for a reasonable price I'd go for it. Thoughts?
