‘After releasing Jon Feliciano and Daryl Williams last week, the Bills had a need for depth up front. The team signed veteran Rodger Saffold last week, and he figures to get the first chance to be the starter at left guard. Mancz figures to get a chance to be the backup center to Mitch Morse. He also provides some insurance in case the Bills aren’t able to retain Ryan Bates, who is a restricted free agent. Mancz has played center, right guard and right tackle during his NFL career.’
