It's finally here.
The biggest sporting event in the Unites States returns as the dynasty that are the New England Patriots take on the unheralded Philadelphia Eagles at Super Bowl LII in Minnesota.
We take a look at three key match-ups that will go a long way into deciding the outcome of the game.
New England Patriots O-line vs Philadelphia Eagles D-line
How much the Eagles' defensive line can disrupt Tom Brady at the line of scrimmage will play a huge role in the outcome of the game.
While they don't boast the number of sacks recorded by teams like the Jacksonville Jaguars or the Pittsburgh Steelers, Philadelphia possess perhaps the greatest amount of depth at the spot.
They are a threat to any quarterback, with the likes of All-Pro defensive Fletcher Cox and Tim Jernigan charging up the middle, and Brandon Graham and Vinny Curry coming off the edge. That's not to mention Chris Long, Derek Barnett and Beau Allen, who can come in at any time and maintain the relentless intensity of the starters.
If Brady and the Patriots have had an Achilles' heel in the past, it's been their inability to deal with the pressure of the opposition's defensive line.
How the Patriots' offensive line deals with the Eagles upfront will go a big way in securing back-to-back championships for the franchise.
Destiny vs dynasty
The Eagles have been the underdogs ever since quarterback and MVP favourite at the time Carson Wentz went down.
The second-year player tore his ACL in week 14 against the Los Angeles Rams and was subsequently ruled out for the remainder of the season.
From then on, they have been subject to immense criticism of their playoff credentials, with few expecting them to win one game in the post-season.
Instead, the Eagles have taken the underdog tag in their stride, even prompting Long and Lane Johnson to wear dog masks after the games.
Once again come Monday, they go into a game the much-less fancied of the two teams, with many already writing them off, and, once again, they will embrace it.
It is a rematch of Super Bowl XXXIX in 2005, where the same two teams squared off for the prestigious title. On that occasion, it was New England who came out victorious, with the ageless wonder that is Brady leading the way.
His opposing quarter-back on that day was Eagles legend Donovan McNabb, a far cry from Monday's Nick Foles.
While he's endured an up-and-down NFL career, the 29-year-old has been sensational in the Eagles' post-season run. Few Eagles fans could have expected the performances he has delivered, including their NFC Championship demolition of the Minnesota Vikings, where he threw for touchdowns and over 350 yards.
The Vikings' defence had held the best third-down conversion rate of any team since 1975, at a rate of just over 25 percent.
Foles would prove the doubters wrong and convert Philadelphia's 10 of 14 opportunities on third-down as they torched the best defence in the league.
In terms of total and passing yardage allowed, the Eagles now face one of the worst defences in the NFL in the form of the Patriots.
Tom Brady and Bill Belichick vs Philadelphia Eagles depth
Brady and Belichick's experience in the big moments during their incredible run of Super Bowl titles will be hard to overcome for second-year head coach Doug Pederson and his team.
If the Eagles are to win, they are going to have to build as big a lead as possible heading into the second half.
The Patriots have shown time and time again, no matter the adversity, they are always a chance to come back and pull off the win. It's simply engrained in their DNA and within the culture of the franchise.
While it's easy to praise the Brady's ability to rise in the big moments, it's Belichick that is the mastermind of it all. His in-game adjustments are second to none, and are often why they play conservative football the first half. They are more than happy to sit back and allow the opposition to dictate the pace of the game and fall into a false sense of security.
It's the second half, and more precisely and importantly, the fourth quarter where the Patriots make the necessary changes and take over.
Despite their undeniable accomplishments, Brady's ability and Belichick's coaching prowess can often paper over the cracks within their roster.
Belichick's built his team around Brady, and rightly so, but they do a pay price in the rest of the assembled squad.
He's relied on gimmicky players - often unwanted from other teams, but deemed appropriate for the scheme - to fill in the gaps, where the Eagles, on the other hand, have quality throughout their roster, and it's their depth that's seen them overcome a long list of injures.
They have been hurt on all sides of the ball and have had to rely on cover for Jason Peters, Jordan Hicks and Darren Sproles from the word go.
An argument can be made the Eagles are better at every position but quarterback and tight-end, where Rob Gronkowski has quickly established himself as perhaps the greatest player in that position.
In terms of offensive and defensive line-play, it's not even a contest, with the Eagles considerably better at the positions. But when you have Brady and Belichick, it may not even matter.
Final verdict
New England's willingness to let the opposition control the opening half will once again come to forefront, gifting Philadelphia the half-time lead.
Brady will do what he does and inspire a comeback, but the Eagles will continue to trouble a suspect Patriots defence and respond with points of their own.
Down by two scores, the Patriots will score a late touchdown deep into the fourth quarter.
Brady will have one final drive to win the game with very little time left on the clock, but will come up short against an elite Eagles defence, forcing an interception.
