Buffalo Bills (6-2) at Miami Dolphins (2-7). From Hard Rock Stadium. Josh Allen improved to 14-2 (including a playoff win) against division-rival Miami after a 31-21 triumph in Week 3, and has found his footing the last two weeks with four rushing TDs and no turnovers in season-steadying wins. James Cook (NFL-best 108.4 ypg) and the Dolphins' De'Von Achane (7 total TDs) star in the backfields. Miami's minus-8 turnover margin ranks 31st in the league.
