Sources: Bucs among teams in on CB

Free agency opened Tuesday, but the New York Jets' spotlight focused on star cornerback Darrelle Revis, who is on the trading block.

The Jets have engaged in trade talks with at least two teams, including the Tampa Bay Buccaneers, according to league sources.

It's unclear if the discussions are serious -- no trade appears imminent -- but the fact the Jets are talking to teams suggests Revis' days in New York could be numbered. Revis receives a $1 million roster bonus if he's still with the Jets on Saturday.

The Jets haven't granted permission to Revis' agents to speak with other teams, sources said -- but that step likely wouldn't occur until the Jets have agreed to trade compensation with another team.

Revis, entering the final year of a four-year, $46 million contract, is looking for a long-term extension that would pay him about $16 million per year.

It's highly unlikely Revis would be traded without a new contract in place. No team would want to give up significant compensation for the possibility of a one-year rental. A clause in his current contract prohibits his team from using the franchise tag, meaning he could bolt as an unrestricted free agent in 2014.

Curiously, the Jets have yet to reach out to Revis' agents to discuss the possibility of an extension, sources said, fueling speculation they've already made up their minds to deal him.

Owner Woody Johnson told confidantes at the start of the offseason that he wasn't optimistic about their chances of re-signing Revis, sources said. At that time, they began to explore the possibility of a trade.

Johnson declined to answer questions about Revis on Monday at an NFL event in Manhattan, saying he'd discuss team matters next week at the league meetings in Phoenix.

The Jets haven't commented publicly since last week, when recently hired general manager John Idzik said Revis is "ahead of schedule" in his recovery from major knee surgery. He also said they're "anxious" for Revis, training in Arizona, to rejoin his teammates.

This looms as a franchise-altering decision for the Jets, who may try to parlay their most valuable asset into extra draft picks with the hope of accelerating the rebuilding process.

Right now, they have only four returning starters on defense under contract. On Tuesday, they released longtime nose tackle Sione Po'uha and lost tackle Mike DeVito to the Kansas City Chiefs. They're also likely to lose free agent Pro Bowl safety LaRon Landry.

At the same time, it's highly unusual for a team to trade a star player in his prime. The knee injury muddles the situation because the Jets will be hard-pressed to receive fair value in a trade, league sources said.

The Jets' initial plan was to be deliberate, waiting for Revis to get healthy. But there could be an increased sense of urgency for both sides, especially if the cornerback market starts to heat up.

It was cool on Day 1 of free agency, as none of the top names changed teams. If anything, the market became more saturated, as Nnamdi Asomugha was released by the Philadelphia Eagles. If teams start filling their cornerback needs, the Jets could lose suitors and Revis could lose teams willing to spend franchise-type money.

The Bucs are a logical landing spot for Revis. They have more than $30 million in cap room, they have a huge need in the secondary and they have two assistants who coached Revis at Pitt -- Dave Wannstedt and Jeff Hafley.

The Jets and Bucs made a blockbuster trade in 2000, with the Jets dealing wide receiver Keyshawn Johnson in exchange for two first-round picks.
