The extension comes hours after the Cleveland Browns agreed to a new four-year deal with superstar defensive end Myles Garrett.
Garrett’s deal is worth $40 million a year, including $123.5 million guaranteed, sources with knowledge of the deal told CNN, making Garrett the highest paid non-quarterback in NFL history.
Allen, who led the Bills to the AFC Championship Game, had a career season as the leader of one of the league’s most potent offenses. Allen passed for more than 3,700 yards and ran for another 531 on the ground, while accounting for 40 total touchdowns.
Allen was drafted in the first round of the 2018 NFL draft out of the University of Wyoming. He’s a three-time Pro-Bowl selection and has been named a two-time All-Pro.
