There's no guarantee that Miller will ever get the call up for game duty, but the 30-year-old will bring in a veteran presence who has a Pro Bowl nod and two 1,000-yard rushing seasons to his credit.
The 29-year-old could be a much better fit in Buffalo as the club only boasts a backfield of Devin Singletary, T.J. Yeldon, Zack Moss and Taiwan Jones.
