Philadelphia Eagles head coach Nick Sirianni implied earlier this week that his job is safe, despite a historic late-season collapse. 

But if we learned anything about the NFL this week, it's that nobody is safe, especially after seeing the Tennessee Titans fire Mike Vrabel and the New England Patriots move on from Bill Belichick after 24 seasons. 

Believe it or not, the Eagles dropping the ball on the No. 1 seed this year was very telling about where the future of the team is headed. 

Eagles' owner Jeffrey Lurie can either ride it out and give Nick Sirianni another year to flip things around, or he can take advantage of one of the best coaching "free agent" classes we've ever seen. 

Here's a look at potential head coach upgrades if Lurie decides to go with option No. 2. 

Mike Vrabel 

The former NFL Coach of the Year joined Tennessee in 2018 where he led them to four straight winning seasons, back-to-back AFC South championships, and clinched the top seed in the AFC in 2021. 

Unfortunately, since then, the Titans have experienced two seasons of losing records, including a disappointing 6-11 finish this year, leaving Tennessee wanting change.

Although things haven't recently gone Vrabel's way, he's done more good than bad for the Titans with a big emphasis on the run game. 

Unlike Sirianni, Vrabel has proven to be a genius in the run game after coaching Derrick Henry to four Pro Bowls and an All-Pro nod. Sure, D'Andre Swift logged his first 1,000-yard season but he still didn't reach his full potential. 

With zero worries about developing a new quarterback, Vrabel could be the guy to maximize Swift's talents and more behind one of the best offensive lines this league has to offer. 

His former NFL playing days in New England and defensive background are also a bonus. 

Bill Belichick 

This man needs no introduction, but we'll give him one. 

17 AFC East titles, nine AFC Championship wins and six Super Bowl rings. 

Not bad, right? 

If there's one thing about Belichick it's that he means business. He would be a huge leadership change if he took over Sirianni's job, but maybe that's what this club needs. 

Sirianni wants to be everyone's friend. Belichick doesn't care. 

It would also help that the Eagles already have a solidified roster, aside from some defense areas, so the 71-year-old wouldn't have to work extremely hard. 

Ben Johnson

Johnson might be too far-fetched with his alleged $15 million asking price but he's still worth talking about. 

The 37-year-old offensive coordinator made history in Detroit, leading them to their first division title since 1993. And to think that four years ago he was their offensive quality control analyst. 

Under Johnson, the Lions' offense finished the season ranked fourth in total offense, fourth in red zone efficiency, fifth in points per game and first in giveaways.

Being superb in red zone efficiency is an Eagles' dream… 

Dan Quinn 

Here we have a defensive guru. 

The Dallas Cowboys defensive coordinator is well known for turning Micah Parsons into a monster, changing him from an off-ball linebacker to an edge rusher. 

He's also well known for blowing the infamous 28-3 Super Bowl lead in 2016 as head coach of the Atlanta Falcons, but that was nearly a decade ago so it's time to move on (haters).

That's the thing, Quinn was already a head coach and has the experience, but he went down and took a DC job for three years in Dallas where learned some more techniques and now he's ready to lead another team. 

Might I add that he's also learned the Cowboys' game plan, which could benefit the Birds, who play them twice a year. 

They could also use a defensive mind since they can't seem to figure that part out. 

Quinn is a player's coach, much like Sirianni, but man when he's mad, he's intense and players are going to want to listen. 

There's also Los Angeles Rams defensive coordinator Raheem Morris and Baltimore Ravens' Mike Macdonald on the head coach market and the possibility of Jim Harbaugh, who just won a College Football Championship with Michigan on Monday, returning to the NFL. 

The opportunities to upgrade your head coach position this offseason are there, but Lurie is a smart man. He's already got to be paying attention and looking out for what's best for the Birds. At least, we hope.
