He's gone. There aren't enough quallified candidates to fill all of the vacancies and if he gets an offer he's taking it. The Jets stint shouldn't reflect badly because it's the Jets. There's him, Vance Joseph, Flores, Kliff, and maybe the Texans DC to fill the Dolphins, Browns, Titans, Giants, Bengals, and potentially the Raiders, Falcons, and Cardinals.
That's not even counting if the Steelers or Ravens decide they need to do a change of scenery firing.....and I personally think the Chiefs job might open up too if they miss the playoffs.
