Winning isn't everything. Winning the Super Bowl matters most.
Sean McDermott became the latest coach to learn that harsh reality when the Buffalo Bills fired him after falling short in the playoffs for the seventh straight season.
McDermott led the Bills to the playoffs eight times in nine seasons, but they didn't make it past the AFC championship game, losing twice to Kansas City.
Now, Buffalo looks for a coach who can help the franchise capture its first Lombardi Trophy.
McDermott turned the Bills into a perennial contender, but couldn't secure that elusive Super Bowl victory so he's out. It happened to Tony Dungy in Tampa Bay, John Fox in Denver, Andy Reid in Philadelphia, among many others.
John Harbaugh was fired two weeks ago after missing the playoffs despite a successful, 18-year run in Baltimore that included winning one Lombardi. He quickly landed with the New York Giants.
Doug Pederson was fired by the Eagles following one losing season that came after three straight playoff appearances, including the franchise's first Super Bowl title.
Marty Schottenheimer was fired by the Chargers after the team went a league-best 14-2 in 2006 but lost in the divisional round.
