Head coaches on the hot seat

With 15 weeks in the books, there are a handful of NFL head coaches who need a strong finish from their teams to avoid the ax at season's end. New York Jets coach Rex Ryan and Tennessee Titans coach Mike Munchak are not among those whose seats are red-hot, but those two still could be kicked to the curb if the final two games go poorly. Tom Coughlin could depart the New York Giants, too, depending on how he and the front office see the Giants' expectations going forward.
