The NFL regular season ended Sunday and on Monday the carnage began.

Romeo Crennel, Cleveland; Eric Mangini, New York Jets; and Rod Marinelli, Detroit are all looking for new jobs with rumors swirling of possible changes in Oakland, Dallas and several other markets.

None of the firings announced Monday were shocking, though Mangini’s axing did come on the heels of a 9-7 season.

Perhaps the most bizarre of the situations was in Cleveland, where owner Randy Lerner announced that Crennel could possibly stay on the coaching staff in another capacity, according to the team’s Web site.

That’d be … awkward.

Many more changes are likely to occur in the near future. Makes me wonder what happened to continuity – look at Pittsburgh, where they change coaches about every other decade. Chuck Noll and Bill Cowher both lasted just short of forever and Mike Tomlin appears entrenched into the future as well.

That organization has five Super Bowl championships and another appearance in the big game. Perhaps that model is something to learn from.
