Mosley had previously spent his entire five-year career with Baltimore after being drafted by the team with the 17th overall pick in 2014.
Through his first five seasons, he has recorded 579 total tackles, 8.5 sacks, nine interceptions, six forced fumbles and one touchdown. He has piled up more than 100 tackles four different times already and never finished a season with fewer than 92.

Prior to the 2018 season, the Alabama product earned a spot in the NFL 100, an honor given to him by his peers.

Mosley let it be known on a number of occasions that he was looking to remain in Baltimore. However, when the Ravens declined to use the franchise tag on him, he had a chance to test the open market, and New York pounced.
The Jets are coming off a season in which their defense ranked 25th in overall defense, 24th against the pass, 26th against the run and 29th in scoring. New York was not alone in trying to lure Mosley away from Baltimore, as the Indianapolis Colts, Cleveland Browns and Washington were also reportedly in the hunt.
