There could be as many after this season, and there are a number of guys on the hot seat.
What there may not be, though, is the usual volume of potential replacements.
One owner who could make a change, and who has spent some time the past couple weeks taking a cursory look at some presumptive future head coaches, told The Sports Xchange this week that the usual pool of candidates from currently successful franchises isn't deep.
"I mean, take a look at the really good teams and give me a name," said the owner. "The best team in the league is Green Bay, and their most recognizable (assistant) is (defensive coordinator Dom) Capers. He's had two (head coaching) jobs already and, while they were difficult situations, no doubt, he was fired from both of them. Can you bring him in and tell your fans, 'Well, the third time's the charm?' I don't know."
The owner noted that, excluding current college coaches, the likely candidates for jobs after this season may fall into two categories: some assistants who may be lesser-known to fans and high-profile former NFL coaches who are working in other capacities.
