Kyle Wilson better prepared if needed to replace injured Darrelle Revis

FLORHAM PARK, N.J. -- The smart money says there's no way Jets cornerback Darrelle Revis will allow the mild concussion he suffered in the opener prevent him from taking the field Sunday in his hometown of Pittsburgh. Of course, the smart money doesn't have to navigate NFL protocol for concussions.

Revis was cleared Wednesday for physical activity but did not practice, meaning he was allowed to lift weights and to run. He also was allowed to speak to the media but postponed a scheduled news conference until Thursday. So, in the absence of any definitive word on his condition, there was this from safety LaRon Landry:

"I have faith he will be there," Landry said of the All-Pro cornerback. "He says he's fine, so, I have faith in him. If he doesn't return, I have faith in the other guys."

Third-year nickel back Kyle Wilson is preparing to move outside to Revis Island in the event the owner isn't home Sunday, and he also might take over punt-return duties if Jeremy Kerley can't play because of lower back stiffness. If he has to cover for Revis, Wilson will be taking on Steelers speedsters Mike Wallace and Antonio Brown.

That's no easy task, but Wilson is far better prepared in his third season than he was as a rookie when he replaced an injured Revis.

"Two years ago, I was just trying to learn," Wilson said Wednesday. "Now, I understand what's coming at me. I've been in this system, so I know everything that's going on as far as what we're doing on defense."

Wilson admitted it was an adjustment to learn the intricacies of the nickel position. But he has settled in after an excellent training camp, and he had one of the Jets' three interceptions of Buffalo quarterback Ryan Fitzpatrick.

"The big thing for me is evolving as the game goes on, taking what you see from film to a game and seeing if what you see in the first quarter holds true or how they've adjusted and how they're going to attack you," Wilson said. "That part of adjusting has changed for me the most."

If Wilson is unsure about anything, all he has to do is ask the guy in the locker to his left. "I sit by [Revis] every day," Wilson said. "I ask him little questions here and there, making sure I'm seeing the right stuff, just bouncing things off him."
