The most important person in the Jets organization this season won’t throw a pass, won’t make a tackle and won’t call a play.

He is a man very few fans have heard of and never gets interviewed by the media.

The most important person for the 2019 Jets is John Mellody, the team’s head athletic trainer. Mellody is in his 24th year with the Jets and is widely revered by current and former players for the care he has given him.

Coach Adam Gase and general manager Joe Douglas will be relying on Mellody to get their players back on the field as quickly as possible after injuries because the Jets are about as deep as an inflatable swimming pool.

If you look at the Jets’ projected starters, this team looks like it could be in contention for a wild-card spot in December. If you remove three or four of those starters, this looks like a team that could be picking in the top 10 again next April.

That point is even clearer after linebacker Avery Williamson was diagnosed with a torn ACL in his right knee on Friday, ending his season before it even began. The Jets will now turn to Neville Hewitt, who has started 11 games in four years, or Blake Cashman, a rookie fifth-round pick.

Most teams in the NFL cannot afford many injuries; the Jets are among them. The lack of depth on this team is the ultimate damning statement on the tenure of former general manager Mike Maccagnan and his predecessor John Idzik. The bulk of this team should come from the drafts of 2013-18. Instead, there is one player left on the Jets from each of the 2013-15 drafts. There are three from 2016 and three from 2017 remaining on the roster.

That kind of drafting left the Jets swimming in salary-cap space last offseason, which many fans celebrated. But if you look closer, it means you have money because you are not re-signing your own picks. Maccagnan landed some core players for the Jets in the first round with Leonard Williams, Jamal Adams and Sam Darnold, but the middle and late rounds produced little.

Gase and Douglas both know the importance of depth on a roster. Gase went 10-6 in his first year in Miami when he had a healthy roster. Then, injuries hit, most notably to quarterback Ryan Tannehill. The Dolphins fell apart and Gase was fired after 6-10 and 7-9 seasons.

Douglas had the opposite experience. The 2017 Eagles were the ultimate example of the value of good backups. Nick Foles famously stepped in for Carson Wentz and led the Eagles to their Super Bowl win. But Wentz was not the only key Eagle missing during the Super Bowl run. Tackle Jason Peters, running back Darren Sproles and linebacker Jordan Hicks were all sidelined.

Other than Williamson, the Jets have not lost any starters for an extended period of time, that we know of. Cornerback Trumaine Johnson (hamstring) and guard Brian Winters (shoulder) both have situations that bear watching and could stretch into the regular season.

The Jets have another week of summer practices and one more preseason game against the Saints to get their starters through (most starters will sit the final week of the preseason).

Then, it will be time for Gase and Douglas to hold their breath and hope their team can stay healthy enough to contend. They will be looking down the bench at Mellody, counting on the trainer to keep their players on the field. So when you start listing important Jets this season — Darnold, Adams, Le’Veon Bell, Robby Anderson, C.J. Mosley … don’t forget to include John Mellody.
