Data from Facebook 'Likes' confirm that the Dallas Cowboys are the most popular NFL team in the United States.

The Pittsburgh Steelers, New England Patriots, Green Bay Packers, New Orleans Saints, Chicago Bears, Indianapolis Colts, Philadelphia Eagles and Oakland Raiders round out the top-10.

The San Francisco 49ers rank 11th behind the Raiders, but have 50 percent fan loyalty in the Bay Area compared to 28 percent for the Raiders.

The Jacksonville Jaguars, St. Louis Rams and Buffalo Bills are in the bottom-three.

There has been speculation of Jon Gruden going to the Dallas Cowboys in 2014 in light of the assistant coaches that have been hired with ties to the former head coach of the Tampa Bay Buccaneers and Oakland Raiders.

The Cowboys have hired defensive coordinator Monte Kiffin, defensive line coach Rod Marinelli, offensive line coach Bill Callahan and special teams coach Rich Bisaccia.

"Ridiculous," said a source from the Cowboys.

The Dallas Cowboys have hired Monte Kiffin as defensive coordinator.

Kiffin was most recently with USC.

Kiffin had a 13-year run with the Tampa Bay Buccaneers.

Kiffin will have to re-tool a defense that has been in a 3-4 scheme since 2005.

Monte Kiffin has been identified as the Dallas Cowboys' preferred choice to become defensive coordinator.

Kiffin has emerged as the leading candidate from a list that also includes Ray Horton, a former Cowboys player and current Cardinals defensive coordinator.

Kiffin resigned as defensive coordinator at USC, where his son Lane is the head coach, and expressed his desire to return to the NFL.

Kiffin would transition the Cowboys from the 3-4 to 4-3, which would involve moving DeMarcus Ware to defensive end.

Rob Ryan has been fired by the Dallas Cowboys as defensive coordinator.

"I'll be out of work for like five minutes," said Ryan to ESPN's Tim MacMahon.

Ryan has been defensive coordinator of the Cowboys since the 2011 season.

Pro Football Focus has announced their All-Pro Team for the 2012 NFL season.
