The Buffalo Bills have locked down their franchise quarterback for the future. On Friday, the team announced it has agreed to terms on a six-year contract extension with Josh Allen, which runs through the 2028 season. According to ESPN's Adam Schefter, the new deal is worth $258 million and includes $150 million guaranteed. 

The Bills originally selected Allen with the No. 7 overall pick in the 2018 NFL Draft out of Wyoming. The 25-year-old is coming off of a career season in which he threw for 4,544 yards, 37 touchdowns and 10 interceptions while leading the Bills to a 13-3 record and an appearance in the AFC Championship Game. Allen ranked fifth in passing yards, fifth in passing touchdowns, fourth in completion percentage (69.2) and had the fourth-best quarterback rating (107.2). His monster campaign broke multiple Bills franchise records, including in touchdown passes, completions and passing yards.

Allen's new reported deal will have him averaging $43 million per year. According to Spotrac, that comes in at No. 2 behind Patrick Mahomes of the Kansas City Chiefs, and just above the $40 million Dallas Cowboys quarterback Dak Prescott will average with his new deal. Allen's $150 million guaranteed and his $100 million fully guaranteed upon signing are both record-breaking numbers, per Ian Rapoport of the NFL Network.  

The big-armed signal-caller has improved in each of his three seasons, and has done enough to prove he is the kind of leader that can take this franchise to new heights. He was the runner-up for MVP in 2020, and is tied for the second-best odds to win the award in 2021, according to Caesars Sportsbook. Allen is the first of the three talented quarterbacks that are expected to sign extensions in the near future. The other two are Lamar Jackson of the Baltimore Ravens and Baker Mayfield of the Cleveland Browns -- who will certainly use Allen's new deal to their advantage at the negotiating table.
