As the Jets get close to training camp, I am going to examine the roster and give you my top 25 players. Each weekday, we will reveal another person on the list, leading right into camp. I am not including rookies on this list because I do not feel it is possible to fully evaluate them before they play a game.

Last year’s ranking: Unranked (not on team)

Position: CB

Age: 28

How acquired: Signed as a free agent to a five-year, $72.5 million contract on March 16

Years left on contract: 5

2018 Salary Cap figure: $10 million

Looking back at 2017: Johnson played under the franchise tag for the Rams and was a key part of their defense. He had 57 tackles, made two interceptions, returning one for a touchdown, and had one forced fumble and a fumble recovery.

Johnson was a solid tackler for the Rams and broke up some passes with his hard hits. He had nine passes defensed.

Pro Football Focus ranked him 75th out of 120 cornerbacks they graded.

Johnson was called for nine penalties (four were declined and one was offsetting), a high number. He was called for illegal use of hands three times and pass interference twice.

The Rams allowed him to walk as a free agent after using the franchise tag on him in two consecutive years.

Outlook for 2018: The Jets targeted Johnson in free agency to bolster their secondary. He was the top cornerback on the market, and the Jets gave him a monster contract.

Big contracts have not worked out for general manager Mike Maccagnan, with both Darrelle Revis and Muhammad Wilkerson flopping after Maccagnan gave them big bucks. Maccagnan has to hope the Johnson signing works out much better.

The Jets have not had a true lockdown cornerback since early in 2012, before Revis tore his ACL. Under Todd Bowles, they had a washed-up version of Revis for two years, followed by Morris Claiborne, who is more suited to being a No. 2 corner, last year.

The addition of Johnson could be game-changing for the Jets defense. If he is able to take away the opponent’s top receiver, it would free up Bowles to be more aggressive with his blitzes. That was a trademark of Bowles’ defenses in Arizona, but he has not been able to be as aggressive with the Jets. If Bowles can dial up blitzes, it could compensate for the Jets lacking a true edge rusher.

Johnson is a nice fit for Bowles’ defense. He has strong man-coverage skills. His addition makes the Jets secondary one of the best in the league. They have Jamal Adams and Marcus Maye entering year two at the safety spots. Johnson playing the No. 1 corner spot pushes Claiborne to No. 2 and Buster Skrine to No. 3, which better suits both of them.
