Former NFL coach Jay Gruden shared a message about Josh Allen as the Buffalo Bills haven't been as dominant as before, with the resurgent New England Patriots challenging them in the AFC East. And fans have started to worry about the reigning NFL MVP's chances to finally make it to the Super Bowl.The Bills lost their third game of the season on Sunday. The struggling Miami Dolphins dominated from start to finish, beating their divisional rival 30-13 in a game that raised plenty of eyebrows around the NFL.On "The Arena: Gridiron" on Wednesday, Jay Gruden lashed out at Allen's team for not maximizing the quarterback's chances to succeed."This Josh Allen's a b*tch," Gruden said. "He is a son of a gun, man. That's a good thing. I don't care who I'm playing, if I look up next to me, I see Josh Allen next to me, I feel damn good about my chances. ... I've been disappointed in the Bills myself. They're soft on defense, and it's very frustrating for Josh Allen to know that he might not get the ball back for another nine minutes in the quarter because the Miami Dolphins are just gutting them."The Bills have lost three games this season, first against the New England Patriots in Week 5. The following week, they succumbed to the Atlanta Falcons. After wins against the Carolina Panthers and the Kansas City Chiefs, they looked ready to dominate the Dolphins, but Mike McDaniel and Co. had different plans.They will face a different challenge in Week 11. The Tampa Bay Buccaneers, who also lost to the Patriots, take on the Bills.Jay Gruden endorses brother Jon Gruden as potential new New York Giants head coachBesides his comments on Josh Allen, Jay Gruden touched on his brother's chances to take over an NFL franchise.
