3. The NY Jets can roll with Jamien Sherwood
One option to consider if the Jets don't re-sign Kwon Alexander is the possibility that they just opt to roll with the young linebackers already on their roster. This wouldn't be my preference, but it's something I could totally see the Jets doing.
The most likely internal replacement for Alexander is Jamien Sherwood, A fifth-round pick in the 2021 NFL Draft, Sherwood has played sparingly over the first two seasons of his career, but he has impressed in limited playing time.
The former Auburn safety started four games as a rookie before a torn Achilles cut his season short. He returned as a backup in 2022 and played just 25 defensive snaps, although he was a core special teamer.
Sherwood has been groomed to be a potential replacement for C.J. Mosley and has served as the team's backup MIKE linebacker. He'd be shifting to a different role in this scenario, but it's one he could thrive in.
Sherwood has shown the ability to be an above-average run defender in his limited action. He is a quick processor and has adapted quite well to his new position in the NFL.
I think Sherwood has genuine starter upside, and trusting him with being the team's third linebacker would be a significant responsibility for the young linebacker. If the Jets feel he can handle it, though, I wouldn't be surprised if they go this route.
Other potential options include Hamsah Nasirildeen, sixth-round rookie Zaire Barnes, and Chazz Surratt, although Sherwood would likely have the inside track to the job.
The Jets' linebacker depth is thin as is, but I wouldn't be opposed to Sherwood taking on a larger role in 2023.
