There’s no question about it: Cornerback is the weakest link on the Jets’ roster right now.

That was probably the case at the start of training camp, when everyone was fully healthy. But now that Trumaine Johnson and his replacement, Kyron Brown, are both injured, the team’s cornerback corps is in a full-blown crisis.

Frankly, the Jets lack both top-end talent and quality depth at the position. Johnson is far and away their best corner. Darryl Roberts, who is playing across the field, is a major question mark as a first-time starter. And Brian Poole, the top slot corner, isn’t a surefire success, either. Then comes the backups, who have just a few hundred snaps of NFL experience – combined.

So, clearly, general manager Joe Douglas has to figure out a way to add talent and fix this part of the roster in order for the 2019 Jets to really have a chance to thrive.

Here are six possible ways that Douglas could upgrade at cornerback – via trades, free-agent signings, waiver-wire additions and more:

Trade for Cardinals’ Patrick Peterson

OK, sure, this may sound strange at first, considering Peterson has rescinded his offseason trade request and is suspended for the first six games of the year. But getting 10 games out of an elite cornerback is still better than none. Plus, Peterson’s contract runs through 2020, so this move would help the Jets for next season, too. So, if anything, the suspension would just help tamp down what would normally be an extremely high trade cost. The risk is that Peterson just turned 29, so the Jets would be getting a player past his prime. Plus, even with the six-game suspension, Douglas would likely have to give up a pretty decent haul to secure his services. It’d be a high-risk, but potentially high-reward, move for the Jets.

Trade for Eagles’ Rasul Douglas

The Eagles are absolutely loaded at cornerback, when healthy. That depth of talent means that Douglas is unlikely to have a big role on this team – despite being a 23-year-old former third-round pick with 30 games of experience over the past two seasons. All of those things add up to making him the perfect trade chip for the Eagles. From the Jets’ perspective, he’s a great fit because he’s young, but knows what he’s doing and is capable of being a starter. Plus, Joe Douglas is familiar with him from his time in Philadelphia; in fact, he played a key role in the team selecting him back in 2017. Again, this comes with a cost, because it’s a trade. But the Jets would also be getting a known quantity, instead of rolling the dice on some of the free agents who are still available for a reason.

Sign Marcus Cooper

The Lions just released Cooper on Monday in order to make room for a younger cornerback. The 29-year-old joined Detroit last season and played four games there, after appearing in two for the Bears. Frankly, Cooper wouldn’t be helpful in the starting lineup. But he’d at least provide experienced depth, which is something the Jets do not have at all right now. Cooper has 74 NFL games and 28 starts under his belt, which is far and away more than all of the Jets’ current backup CBs put together. For that reason alone, he could be a useful addition to the room.

Sign David Amerson

Amerson was a surprise cut at the end of OTAs. The Cardinals decided to let him go because they felt their other options were good enough to fill in for Peterson. But entering the spring, the expectation was that Amerson would help fill that void. So, the 27-year-old can’t be all that bad. He played six games and started five last season, after playing and starting six in 2017 for the Raiders, too. In 2016, he was a mainstay in the Oakland lineup, starting 15 games. He’s played 74 games and started 61. In other words, he could probably provide some competition for Roberts in that second cornerback spot. Or, at the very least, he could serve as a useful backup, in case injury strikes this unit again come the regular season.

Wait for Browns/Eagles/Bengals competitions to wrap up

We already mentioned that the Eagles are deep at corner. The Browns and Bengals both seem to be in the same boat. So, odds are that some, if not all, of those teams will make some cuts at cornerback once training camp wraps up. If Joe Douglas stays patient, he may be able to scoop up some of the leftover talent off waivers or the free-agent market. This strategy comes with some risks, though; there’s a chance that other teams could beat the Jets to the punch, either with a better waiver priority or more lucrative contract offer. Plus, the talent available could be more back-end worth, as opposed to some of the names on this list so far, who could either serve as starters or decent backups.

Move Jamal Adams

Adams said Monday that he’s confident in the Jets’ current cornerbacks to get the job done. But He also said that he’d happily move to cornerback, if asked.

To be clear, we don’t expect the Jets to slide their Pro Bowl safety into a different role anytime soon; his ability to get in the box and make plays in the backfield is too valuable to sacrifice, at least for right now. But, Adams has proven to be a very good coverage safety, so it isn’t the craziest idea, if the Jets can’t find the proper outside talent to get the job done. The biggest issue with this plan? Having to insert Rontez Miles back into the starting lineup alongside Marcus Maye. This unconventional move would work a lot better if the Jets were deeper at safety.
