‘The Bills enter Sunday’s game at MetLife Stadium leading the league in takeaways (16), interceptions (12) and turnover margin (11). Their opportunistic defense, which has returned a league-leading three interceptions for touchdowns, picked off both Tom Brady and Michael Vick four times, propelling Buffalo to a 4-1 record and a tie atop the A.F.C. East with the New England Patriots, whom they defeated earlier this season.’
