The Jets injury problem was so bad in 2019 that the trainer’s room barely had enough space for all of the rehabbing players, who had to schedule their times with trainers to avoid a logjam.

Now, the Jets are trying to figure out if there was a reason for all of those injuries or if it was just bad luck. Jets coach Adam Gase said they began looking at what was causing all the injuries about two months ago.

“I wish it was cut and dry and say, ‘Hey we had 15 hamstrings,’ ” Gase said. “But we’re having season-ending-type injuries. We’ve had discussions with the training room, strength and conditioning; [general manager] Joe [Douglas] and I have had conversations; we’ve talked to other people. We’re going to continue to take deeper dives and all that when we meet with the staff as far as was it practice schedule, training camp, offseason. Is it something we’re doing during the season? We’re combing through everything because we can’t have this happen again.”

The Jets had a staggering amount of injuries. Here are some eye-popping numbers:

They used a franchise-record 73 players. Only the Dolphins and Redskins used more this season.

They had 20 players wind up on injured reserve.

They used 11 starting offensive linemen. They had nine starting combinations on the line. They had three starters each at left guard and right guard.

They used four quarterbacks and three starting quarterbacks. It was the first time since 2005 they had four quarterbacks take a snap.

Four players viewed as key starters in the preseason ended up playing two games or less — ILB C.J. Mosley (2 games), TE Chris Herndon (1 game), WR Quincy Enunwa (1 game) and ILB Avery Williamson (0 games).

The Jets used six starting cornerbacks on the outside (not counting nickel corner Brian Poole). They used five starting inside linebackers.

All of this contributed to the Jets’ 7-9 season. They failed to overcome many of these injuries in the first half of the season but handled them much better in the second half.

The Jets need to consider whether changes need to be made to their medical or strength and conditioning staffs, although Gase indicated that is highly unlikely.

Practice rules in the NFL are highly regulated by the collective bargaining agreement. There are limits on offseason practices and how often you can wear pads in practice. That makes it unlikely Gase is running practice any differently than other teams when it comes to contact and the length of practices.

“Without having all of the facts, my initial thought is that this year is a bit of anomaly as far as the amount of injuries that we sustained as an organization, as a team,” Douglas said. “We are in the midst of that research; we are doing a deep dive to as far to what we can do to prevent this from happening again and what we need to implement to make sure that this amount of injuries doesn’t happen.”

The Jets have plenty of priorities this offseason. Figuring out a solution to their injury issue, if there is one, should be near the top of the list.
