Sure he can. But i don't see him being the workhorse the Bengals want us to believe he is. They're touting him as a three down back....i'm not sure he can hold up to it. He was used sparingly in New England for the most part.
And if it's me, i'm keeping my best talent and targeting rookie RBs like Richardson, Martin etc...AND guys who may not be kept like Lynch, Spiller, J Stew, possibly DeMarco Murray...etc. With only two keepers, there will be RBs to be had.....you don't need to "settle" for BJGE on value alone when you have more talented players to keep on your roster.
