NY Jets: 4 more free agents who would improve the roster

3. The NY Jets could sign LB Kwon Alexander

Just as the Jets are going young at cornerback, they seem intent on doing so at linebacker as well. At least, at weakside linebacker.

C.J. Mosley will return after what has essentially been two years away from the game. He'll look to live up to his massive contract in what will hopefully be his first full season with the organization.

The Jets also signed former Detroit Lions draft bust Jarrad Davis, who will take over the SAM role in Robert Saleh's defense while also serving as the primary backup MIKE.

As for the weakside role? That remains undetermined.

At the moment, it's expected to be a three-way battle between the oft-injured Blake Cashman and Day 3 picks Jamien Sherwood and Hamsah Nasirildeen.

The Jets are hoping that Sherwood or Nasirildeen could step up and win the job, but they could certainly use a veteran like Kwon Alexander to sure up the position.

Alexander has experience playing under Saleh as he did so in San Francisco and the athletic linebacker excelled in his system — when he was on the field.

Unfortunately, injuries have taken their toll and Alexander is coming off a torn Achilles he suffered in December of last year. At the time of writing, he is hoping to be healthy for Week 1.

It's unclear if Alexander will still be the same player after his injuries, but he's worth the gamble at a small price.

If he's even 75 percent of the player he once was, he'd easily be the best weakside linebacker on the roster and someone who could play in the nickel if they don't trust Davis in coverage.
