Mosley agreed to leave the Baltimore Ravens for a five-year, $85 million contract from the Jets that includes $51 million of guaranteed money, NFL Network and nj.com reported on Tuesday morning.
As for Mosley, the Jets are signing one of the premier inside linebackers in the league.
Let's get to know the Jets newest addition. It was the fourth year Mosley finished with more than 100 tackles.
The Washington Redskins and Cleveland Browns were also thought to be interested in Mosley.
Mosley hit the open market after the Baltimore Ravens, who he spent the first five seasons of his career with, decided not to place the franchise tag on him.
Mosley has made 597 tackles, nine interceptions and 8.5 sacks since joining Baltimore from Alabama as the 17th player picked in the 2014 NFL Draft. The Jets offered more money, but the pull of remaining with Minnesota, the team that drafted him, was too great for him to join the Jets.
The Jets felt they needed a "mike" linebacker for new defensive coordinator Gregg Williams, a man in the middle to run the defense. Lee, who was selected with the 20th overall pick in 2016, could fill that void. His play did improve last season but his four-game suspension was likely his ultimate downfall.
Lee has one year left on his rookie deal, and it would appear unlikely the Jets will pick up his fifth-year option for 2020 - even without Barr coming to NY.
Bucs linebacker Kwon Alexander reached a four-year, $54 million deal with the 49ers despite the fact he's coming off a torn ACL.
Mosley, who turns 27 in June, can also help in the locker room.
