Rex Ryan heads into the weekend with the extension he desired. [But] it also came with a message. Win now ... or else. Ryan, whom many had heading for the unemployment line in Week 15 this season, and the Jets agreed to an multi-year extension -- sort of. Though technically a multi-year extension, in reality Ryan's contract fully guarantees his salary only through 2015, according to a source. His old deal ran through the 2014 season. The extension gives owner Woody Johnson and general manager John Idzik an opening to can Ryan, as the coach's salary beyond 2015 is not fully guaranteed -- if at all. The deal includes playoff incentives, according to a source. "I'm no different than any of our fans," Ryan said in a statement. ... "I'm an ordinary guy that's been given an unbelievable opportunity." Source: New York Daily News
