Rex Ryan’s perfect 53-man roster would probably include 52 cornerbacks (and one quarterback), so there’s no telling what was swimming around in his head when one of the players he’ll need to rely on the most in his secondary looked downright lost in the preseason opener against the Colts on Thursday.

Revis Island and Al-Cro-traz have relocated, leaving a head coach who has had man-crushes on cornerbacks for the better part of his professional life with a sobering truth: His secondary could be in for a very long season.

There’s a new No. 24 in town and that isn’t a good thing.

Journeyman Dimitri Patterson won’t ever be confused with Darrelle Revis, but his sloppy Jets debut raises concerns that shouldn't be ignored. The 31-year-old cornerback gave up three receptions for 59 yards, including a pair on third down. He made Colts third-stringer Da’Rick Rogers look like Marvin Harrison on a 45-yard pickup.

“Whether you have a bad preseason or a great preseason, when the regular season comes, you have to perform,” Patterson said. “That’s what everybody remembers.”

It’s too early to panic, but Patterson’s poor play wasn’t confined to his 38 snaps against the Colts. He’s been struggling for much of training camp with “nagging injuries” to his ankle and calf and an inability to consistently win one-on-one matchups.
