"With any starter, it gets to the point in the week where you got to say, 'Hey, we're going to have to go one way or the other,'" McDermott said, per Mike Rodak of ESPN. "We'll cross that road when we come to it at this point."
"He is ready," McDermott said. "When you look at what he's done throughout the preseason, I'm confident and we're extremely confident in Nathan. I expect that he's only going to continue to get better."
McDermott's assessment comes days after first-year general manager Brandon Beane glowed over Peterman, calling the former Pittsburgh star "better than I expected."
"The moxie, the pocket presence, the leadership," Beane said of the rookie, before noting that Peterman "seems to be natural" at leading a football team.
It's easy to imagine the Bills using multiple starters this season, especially if they want to examine Peterman before next year's quarterback-rich draft forces Buffalo to make a decision that could effect every signal-caller on the roster.
