The Washington Football Team defense was the unit that carried the franchise to an NFC East title in 2020, and the front office has now rewarded one of their most important players with a huge extension. On Monday, Team IFA announced that their client, defensive lineman Jonathan Allen, had agreed to terms on a four-year, $72 million extension with a $30 million signing bonus.

Allen continued to prove he is one of the best defensive linemen in the NFL last season, as he recorded 63 combined tackles, two sacks and 14 quarterback hits in 16 games played. Jared Dubin of CBS Sports ranked Allen as the No. 10 best interior defensive lineman in the NFL entering the 2021 season. While he didn't rack up sacks in Washington's new defense last year, he ranked 19th among interior defenders (out of 137 who played 25-plus snaps per game) in WOW Rtg. Allen confirmed the extension on Twitter following his agency's announcement. 

These reported contract numbers would make Allen the fourth-highest paid defensive tackle in terms of average salary ($18 million) -- per Spotrac. JP Finlay of NBC Sports Washington says the contract is more like a five-year, $82 million deal due to the fifth-year option in play for 2021. That drives the AAV down to $16.4 million instead of $18 million.

Allen played his high school ball close to Washington's headquarters at Stone Bridge High School in Ashburn, Virginia. He committed to Alabama to play under Nick Saban, and won the CFP national championship in 2015 and was named the SEC Defensive player of the Year in 2016. After an illustrious collegiate career, Washington took Allen with the No. 17 overall pick in the 2017 NFL Draft after his stock fell due to concerns about medicals. While he missed most of his rookie season due to injury, Allen lived up to expectations in Year 2, and has missed just one game over the last three seasons. In 52 career games, he has recorded 202 combined tackles, 17 sacks and 45 quarterback hits.

Allen's production as a defensive lineman clearly stood out to those in the Washington organization, as they selected a defensive lineman in the first round over the next three drafts. Now, with a front four which includes Allen, Montez Sweat, Chase Young and Daron Payne, Washington has what is seen as the best defensive line in the NFL.
