Tom Coughlin and the NFL's 4 Biggest Dead Men Walking After Week 15

The 2011 NFL head coaches graveyard has fresh plots filled by Jack Del Rio, Todd Haley and Tony Sparano already this season.

There will likely more victims joining their fallen brethren when the season concludes.

Whether the excuse is "failing to meet expectations" or "wanting to go in new directions," the axe is going to fall on some or all of the following head coaches.

Tom Coughlin

It will be a shame if the New York Giants waste one of Eli Manning's finest seasons as a professional.

The only person who will suffer for that is Tom Coughlin. The odds were stacked against Coughlin and the Giants from the start due to injury on defense, but a loss to the hapless Redskins this late in the season is unacceptable.

Nothing short of a berth in the Super Bowl might save Coughlin, but he has heard that before in New York and survived.

Steve Spagnuolo

Steve Spagnulolo, Sam Bradford and the Rams were primed for a coming-out party this season after narrowly missing the NFC West title last season.

What a difference a year makes, because now Spagnuolo has to be wondering if he is still a part of the Rams' future plans.

Bradford has battled injuries and a lack of a supporting cast in the receiving game, but Spagnuolo has done a less than admirable job in keeping the battered Rams respectable this season. 

The Rams may be serious contenders for the first overall pick, and with that might come a complete overhaul of the team from the head coach down.

Raheem Morris

No team has been more frustratingly inconsistent than the Tampa Bay Buccaneers. Another team with great potential that buckled under incredible expectations. 

Raheem Morris has been praised for his infectious energy and attitude, but with speculation that he lost the locker room, there have also been whisperings that the Bucs may have already tried to fire Morris.

Young talent like Josh Freeman and Legarrette Blount will not go wasted in Tampa Bay, and Morris is more likely to go in an attempt to get the most out of their combined efforts.

Leslie Frazier

The Vikings thought they had the right man in waiting under Brad Childress when they promoted Leslie Frazier to head coach. 

Frazier has been given a pass up until this point because of the giant mess that was left in the wake of Brett Favre's departure from Minnesota. Now, though, the blame could be falling directly on Frazier for the lack of progress that the Vikings have shown this season.

A commitment has already been made to Christian Ponder, and that is widely regarded as a shrewd move. It may be a different head coach guiding Ponder and the Vikings in 2012, as the same vote of confidence has not been given to Frazier.
