Washington detailed their multi-year offer to Kirk Cousins this offseason after they were unable to come to an agreement.

"Our goal was to sign Kirk to a long-term contract with the final objective of having him finish his career with the Redskins," Allen said Monday in the statement. "On May 2, right after the draft, we made Kirk an offer that included the highest fully guaranteed amount upon signing for a quarterback in NFL history ($53 million) and guaranteed a total of $72 million for injury. The deal would have made him at least the second highest-paid player by average per year in NFL history.

"But despite our repeated attempts, we have not received any offer from Kirk's agent this year. Kirk has made it clear that he prefers to play on a year-to-year basis," Allen said. "While we would have liked to work out a long-term contract before the season, we accept his decision."

Cousins will become the first NFL quarterback to play under the franchise tag for a second consecutive season, earning $23.9 million. 

Cousins' side didn't counter the initial offer, knowing if he was franchised he'd make $23.9 million guaranteed -- and then hit free agency in 2018, or be tagged again.
