No matter what happens during the 2012 NFL season, one thing is certain: Head coaches will be fired.
The NFL is built on parody with nearly a 50 percent turnover on playoff teams each year. Therefore, most teams will seriously consider change after two non-playoff seasons. For teams that are constantly losing like the Buffalo Bills or Cleveland Browns, that number may go up to three seasons.
But these coaches are not just the ones that fail to make the playoffs. This list includes coaches who have made the playoffs and even several that have played in conference championships. But they have not delivered lately and this leaves their franchise's owners very unsatisfied.
Here are the coaches that I think are on the hot seat in 2012. They will need to at least lead their teams to a playoff berth, perhaps even a deep playoff run to maintain their jobs. If not, we can expect them to go and their teams to start all over with new coaches.
