Looking at the numbers, NFL teams aren't very good at hiring coaches. We know the Oakland Raiders are good for a coaching change every other year or so but the 2009 hiring season in particular looks really, really brutal.
Those new head coaches that are now gone include Haley, Tom Cable, Mike Singletary, Steve Spagnuolo, Raheem Morris, Eric Mangini, Josh McDaniels and Jim Mora.
2009 seems like a lifetime ago with some of these guys. Jim Mora? I forgot he was the head coach in Seattle for a year. Haley, Spagnuolo and Morris at least lasted until this season.
