‘How the Bills will use LeSean McCoy, 31, and Frank Gore, 36, will come better into focus after this game. The Golden Boys had six combined carries for 13 yards against the Colts and Panthers. Rookie Devin Singletary is the starter in waiting, leaving Marcus Murphy, T.J. Yeldon, Senorise Perry and free-agent sensation and everybody’s favorite former rugby player Christian Wade battling for one spot. Perry is nursing a tender ankle.’
