NFL Rumors: Latest on Mike Smith, Tom Coughlin and Jim Caldwell

The first domino has fallen in the NFL's coaching carousel. Adam Gase will be the next head coach of the Miami Dolphins.

Now, the attention turns to some other notable vacancies.

Tom Coughlin resigned as the New York Giants' head coach, but a division rival might be swooping in to sign him. Meanwhile, the Giants are looking at a former coach who led the Atlanta Falcons to the NFC Championship Game not too long ago.

Here are the latest rumors in the coaching world.

Eagles Hoping to Interview Tom Coughlin

The Philadelphia Eagles want to hurt the Giants right in the heart.

Looking for Chip Kelly's replacement, the Eagles will request permission from their division rivals to interview the two-time Super Bowl winning coach, according to ESPN's Adam Schefter.

The Eagles need to ask for permission because Coughlin resigned, and he was not fired. Coughlin has one year remaining on his deal with the Giants, and if a team should want to interview him, it would need to take on the $7 million Coughlin agreed to back in March.

Schefter has been told by sources that the Giants will allow the Eagles to interview Coughlin, should he want to speak with them.

The ESPN report linked above also noted that Coughlin is "intrigued" by the Eagles job, per ESPN's Dan Graziano.

At 69 years old, it's unclear how much longer Coughlin wants to coach or how much longer he can coach. Given the right situation, Coughlin could coach out one last contract before deciding to end his Hall of Fame career.

The Eagles would be an intriguing situation, though. There's uncertainty at quarterback, not knowing if Sam Bradford will want to be in Philly next season. Coughlin could turn the Eagles into his vision of a power-run team, while also utilizing the most of DeMarco Murray and Ryan Mathews.

If there's a situation that could appeal to Coughlin the most, it would surely be Philadelphia.

Mike Smith to Interview with Giants

Meanwhile, the Giants continue life without Coughlin. New York plans to bring in former Atlanta Falcons head coach Mike Smith for an interview on Monday, per NFL Media's Ian Rapoport.

Smith spent seven years as the head coach in Atlanta, coming in the same year the Falcons drafted Matt Ryan with the third overall pick in 2008. Atlanta recorded a winning season in Smith's first five years, with the last resulting in a trip to the NFC Championship Game in 2012 before losing to the San Francisco 49ers.

The Falcons have not been the same since that season. Atlanta went 10-22 in the final two seasons under Smith before he was fired in 2014.

When Smith was succeeding, defense was the calling card. The Falcons finished in the top five twice in scoring defense, and in the top half of the league four times. When he has a healthy, talented team, Smith is a good coach.

If Smith takes the Giants job, he'll have an offense he can work with. Eli Manning is getting older, but he can still play at a high level, given some offensive balance. The Giants need to establish a running game, which will be a top priority for whomever steps in.

The Giants need a fresh defensive-minded coach. New York finished in the bottom half defensively the last three years, including 30th in scoring defense and dead last in yards allowed. If New York wants to go defense, Smith would be a good hire.

Jim Caldwell's Job Security In Question, After All

The Detroit Lions hired Bob Quinn as their new general manager on Friday, and that could mean trouble for Jim Caldwell's future with the Lions.

Rapoport is reporting that the hire of Quinn has made Caldwell's future far from certain, per NFL.com's Marc Sessler. 

This is an interesting development, considering Rapoport noted last week that the Fords treated Caldwell like he would be back next year. Rapoport also said the new GM would make the final decision.

After starting the season 1-6, Caldwell and the Lions won six of their last eight games, which appeared to secure his status for next season. Although there were no playoffs, the Lions rallied around Caldwell and finished strong.

If the Fords have any leeway in these discussions, though, their vote of confidence toward Caldwell should go a long way in Quinn's decision.
