Revis played for the Jets from 2007-2012 and quickly earned a reputation as one of the best cornerbacks in the NFL. He has been named to six pro bowls (four with the Jets), first-team all-pro four times (three with the Jets) and won the 2009 Defensive Player of the Year award.
The Jets traded Revis to the Tampa Bay Buccaneers before the 2013 season. Despite signing a 6-year-contract with the Buccaneers they released him after just one season. The Patriots then signed him as an unrestricted free agent to a two-year deal.
If the Patriots decline to pick up his $20 million dollar 2015 option then Revis will once again become an unrestricted free agent.
Unless the Jets offer Darrelle Revis the $16 million a year he wants, there's no chance that the Jets will get him back into the fold. Revis just won the Super Bowl and will want to return to the Patriots, just at "his" price. This is nothing more than his agents using scaremongering to get what they want. As best I can tell, Adam Schefter can't speak on this matter while Revis's agents, Schwartz & Feinsod drink a glass of water.
Schefter is being used rather transparently to drive up the price on Revis in the lead-up to the Combine, the unofficial start of free agency.
