‘The trade of McCarron, coupled with the Bills not adding another QB over the weekend, leaves the team with only two signal-callers for the time being. McDermott said that in addition to Allen being the No. 2 QB he will also run the team’s scout-team offense during the week against the team’s starting defense. He also mentioned Logan Thomas as a potential emergency QB if the need arises. Thomas played quarterback at Virginia Tech and briefly in the NFL before converting to tight end.’
