Philadelphia, PA (Sports Network) - At least they know when the anvil will drop on their heads.

It will be two weeks from yesterday when more than a few NFL teams decide they've had enough with their current coach and his regime and will make a change.

Undoubtedly, Dec. 31 will be "Monday, Bloody, Monday" across the NFL Nation. (And, I apologize for the incorrect U2 song reference, but it just kind of fit).

It's the same story the day after every regular season ends. The names and teams change, but the press conference is always the same as some team exec will say: "We're just looking for a change in direction."

The big question is how many teams will make the change?

You could make an argument that 11 current coaches could be ex-coaches in less than two weeks. Now, that number is likely too high, and the argument to axe some of these guys is flimsy, but does anything an NFL owner does when his team is struggling truly surprise you?

And what if that's the case? The league only has 32 teams and over a third of the coaches could be gone? Wow.

Let's take a look at the "could be" unlucky 11 in order of who is in the most trouble.

Andy Reid, Philadelphia Eagles: The longest tenured coach in the league probably already has his bags packed. After his team went 8-8 last year, owner Jeff Lurie said his Eagles had to make marked improvement in order for Reid to keep his job. The Birds haven't done that, meaning Reid will go. For his sake, he won't be unemployed long and will be back on an NFL sideline in 2013.

Norv Turner, San Diego Chargers: Every year the Chargers are picked to be a Super Bowl contender and every year they're not. Same story this year. It's time for a change. Look for Reid to replace Turner.

Ron Rivera, Carolina Panthers. You have to feel badly for Rivera considering this is only his second season in charge, but impatience is part of the NFL. This team, and Rivera, needed Cam Newtown to take a big step and the defense to improve. Those things didn't happen.

Pat Shurmur, Cleveland Browns: Like Rivera, Shurmur is only in his second season, but the team was sold in October and the house will be cleaned. Cleveland has a ton of talented rookies that Shurmur won't have a chance to develop.

Ken Whisenhunt, Arizona Cardinals: The Cards jumped out to a 4-0 start and then just went in the dumper. Quarterback injuries and dissension will do Whisenhunt in.

Mike Munchak, Tennessee Titans: Munchak may be the third guy with only two seasons in charge to be told to collect his things. If this happens, it would be just amazing to see another short termer let go so soon.

Rex Ryan, New York Jets: Ryan is a breath of fresh air because he speaks his mind in a league full of coaches that don't. But all of his bluster, plus a bevy of problems in New York could spell the end.

Chan Gailey, Buffalo Bills: He's only had three seasons at the helm, and I don't think he'll go, but stranger things have happened in the coaching business.

Mike Mularkey, Jacksonville Jaguars: This is his first season and it might be his last. If that's the case, and I hope it's not, the guys who brought him in should also follow him out the door.

Jim Schwartz, Detroit Lions: A lot was expected of the Lions this season and they didn't deliver. Will that mean the end for Schwartz? It shouldn't, but.

Romeo Crennel, Kansas City Chiefs: Crennnel is a good coach in his first year with a bad team. Add in the tragedy with the recent shootings and Crennel has to return, no questions asked.

OK, with all of these vacancies, who do teams find to fill them? Jon Gruden can't go everywhere, so all of you assistants, and college coaches, get your resumes ready fast.
