Projected Starters: Wesley Johnson, Brian Winters, James Carpenter, Ben Ijalana, Kelvin Beachum
Projected Back-ups: Brandon Shell, Dakota Dozier, Brent Qvale
On the bubble: Jeff Adams, Ben Braden, Chris Bordelon, Javarius Leamon, Craig Watts, Alex Balducci, Jonotthan Harrison
Departures: Nick Mangold, Breno Giacomini, Ryan Clady
Key stat: The Jets used nine different combinations of starters over the course of the season and never went longer than three weeks without having to make a change.
The Jets' offensive line was in flux all season last year, as four of the five opening day starters ended the season on injured reserve. The projected starting tackles - Clady and Giacomini - played just one game together in week eight and both are now off the team. Mangold will be a much bigger loss, but his durability has been an increasingly significant issue over the past few seasons. He started just one game after week seven and was banged up even when he played, leaving the line searching for chemistry and cohesion.
The one constant over the past two years has been Carpenter, who has started 32 straight games and been the team's most reliable performer on the line. Signing Carpenter has been one of Mike Maccagnan's best moves and now the team will look to him to provide some leadership this year.
At the other guard position, Winters started 13 of the first 14 games before ending up on injured reserve. He's improved a lot over the course of his career but can still go through stretches where he gets beaten or makes mental errors at key moments. The Jets will need him to avoid such issues as much as possible if he's to justify the $7 million per year contract they invested in him after the season.
In between the two veteran guards, Johnson will enter the season as a projected starter for the first time. He had some initial struggles filling in for Mangold, but seemed to grow into the role as the season progressed. Earlier on in the year, Johnson - who was once released by the Jets in 2015 - had filled in admirably at guard when Carpenter was knocked out of a game.
At tackle, the Jets invested significant money in Beachum and Ijalana. Beachum started all 16 games for Jacksonville coming off a serious knee injury, but struggled in the running game and gave up a lot of pressure. He lacks size and needs to rely on technique to be effective, so if he's still limited physically then it might be difficult for him to emulate his solid play from his Pittsburgh days. Ijalana started off at right tackle and then moved over to the left when Clady went down. Like Johnson he grew into his role as the season progressed.
Over the last two games, youngsters Shell and Dozier started on the right side and performed well. Shell will compete with Ijalana for a right tackle role and has a good shot at getting more starts if Beachum can't remain healthy all year. It seems less likely that Dozier could get a shot to start with the highly paid Winters and Carpenter ahead of him, but his ability to also fill in at center makes him a valuable reserve.
Qvale has also proved himself to be a useful reserve over the past few seasons, making a few spot starts and rotational appearances at guard, tackle and in jumbo packages. The Jets may be hoping for at least one of this year's undrafted rookies - Braden, Bordelon and Leamon - to provide them with similar low cost depth within the next few years.
The versatile Watts is the only other holdover from last year's team, although he has played just five offensive snaps in his career.
Harrison was signed from the Colts and has started 23 games over the past three seasons at center and guard so he could be in the mix to back up Johnson. Adams was actually an opening day starter in 2015, but has just two career starts with the Texans and has to be considered a long shot.
Finally, Balducci is probably a long-term prospect at best, as he was a defensive tackle in college who didn't begin the transition to offensive line until last season.
Outlook: The offensive line is another area where the Jets are expected to struggle but they have several players who held up quite well last year. If they can just remain healthy, they'll have a chance to build some chemistry and could surprise. The success of the line may hinge on how well Johnson anchors the line at center. Beachum's durability is also a major concern, although the team will hope they are well-equipped to handle any short term absences.
