Boyle, 28, who finished last season on the Chicago Bears' roster, will be reunited with offensive coordinator Nathaniel Hackett. They overlapped for the 2019 and 2020 seasons in Green Bay, where Hackett served as the coordinator from 2019 to 2021.
The Jets also made an addition to their defensive line, signing defensive tackle Quinton Jefferson on Thursday. The team did not disclose terms of the deal for Jefferson, who was released by the Seattle Seahawks in March.
Jefferson, 30, played in all 17 games last season and made three starts. His 5.5 sacks and six tackles for loss were both career highs.
He becomes the favorite to replace starting defensive tackle Sheldon Rankins, who signed with the Houston Texans, although the Jets could address the position further in the draft. The Jets made unsuccessful attempts to sign Fletcher Cox and Calais Campbell before turning their attention to Jefferson.
Boyle joins former No. 2 overall pick Zach Wilson and Chris Streveler, a former practice-squad player, in the Jets' quarterback room. Wilson will be the No. 2 quarterback, coach Robert Saleh said last week at the annual league meetings. Boyle provides veteran depth and familiarity with the system, which will help in the installation of the new offense.
Saleh carried three quarterbacks in each of his first two seasons, so it's not unusual for the Jets to add a veteran. Essentially, Boyle replaces Mike White, who signed with the Miami Dolphins as a free agent. Backup Joe Flacco remains unsigned.
Boyle spent three seasons with the Packers, making the team in 2018 as an undrafted free agent out of Eastern Kentucky. Playing behind Rodgers, the NFL MVP in 2020, he attempted only four passes during his time in Green Bay. Nevertheless, he made a strong impression on Rodgers.
"He's just a special guy," Rodgers told Green Bay reporters in 2021, when Boyle was preparing for his first career start as a member of the Detroit Lions. "I watched him grow and develop over the years with us, not just as a person, but as a player. He's got a big-time arm, and he's very athletic, as well."
Boyle lost all three starts for the Lions in 2021, completing 61 of 94 passes for 526 yards, three touchdowns and six interceptions. He was released in the 2022 preseason and was eventually signed by the Bears on Nov. 30. He appeared in only one game for the Bears, throwing two interceptions in mop-up duty in the final game of the season.
