KANSAS CITY, Mo. -- Even by his own acknowledgment, Darrelle Revis didn't play as well in his brief trial this season with the Kansas City Chiefs as he did earlier in his career. Then, he was a shutdown cornerback and his teams were so confident in his ability to cover without help that he earned the nickname "Revis Island."

But for a 32-year-old who didn't practice or play until late November, when he joined the Chiefs, Revis played well enough that he wants to return for a 12th NFL season in 2018.

"The material I put on [videotape] from the little time I had, not going through training camp and being here for the installs, I was OK," Revis said. "I wasn't great or my best ever. No way. But at the same time, for what I came in here and was asked to do, for the most part I'm happy with it.

"My situation is a little different than most. We all understood that coming in. I was trying to get on the same page with what the team was doing and playing catch-up basically. ... Always room for improvement. But when you look at some of the stats, no touchdowns allowed ... ."

Revis joined the Chiefs on Nov. 23 and played in five games in the regular season plus the playoff loss to the Tennessee Titans. He started two games and otherwise was the third cornerback behind Marcus Peters and Steven Nelson.

"I think it's pretty remarkable what he has done considering he had no camp, no [anything] and he just dropped in here," defensive coordinator Bob Sutton said before the playoff game. "It's just getting back in that kind of condition and that type of reaction time and I think each and every week he's been out here he's been better from that regard. He's a great technician throughout his entire career and I think that's starting to come back little by little each week. Hopefully, he's another guy who keeps ascending right now.”

Revis has one more season left on his Chiefs contract at $10 million. That's a steep cost for a cornerback who isn't playing like one of the best in the NFL.

But the Chiefs aren't in position to turn away a talented cornerback. The volatile Peters was suspended for a game this season and at times seemed more interested in engaging coaches, officials and fans in heated discussion. Nelson missed half of the season after having core muscle surgery and was up and down after his return.

"You never know with these things," Revis said. "This is my fourth team. Rosters always change. Even if we went the distance and won the Super Bowl, that team changes as well. I understand the situation.

"I'm always optimistic about these things. I'm just being optimistic and if the opportunity presents itself, you take the opportunity."

Whether he's with the Chiefs or another team, Revis said he plans on participating in offseason practice and training camp next season.

"I was out for almost a whole year [by the time of the signing with the Chiefs]," he said. "You have to weigh those types of things in. No player can come in and just make plays being out for a year. I missed [offseason practice]. I'm the type of guy that I'm here for [offseason practice], here all the way to camp. You have to put all of those things in consideration. I didn't go to training camp. I remember I held out from training camp one year a few years back and I was even young back then and it still affected me when I came back.

"I just feel like if I had been here during those [offseason practices] and training camp practices I would have had more reps and been more comfortable. I still think I can contribute. I think a lot of people kind of criticized me because of how I played in the past but for the most part the role I played here was simply to contribute. The role coach gave me was to play nickel and that's what I came to do."
