This is the first Super Bowl of the Los Angeles Rams since 2001, and many people are not giving the underdogs a chance.
Jared Goff is the fourth youngest quarterback in Super Bowl history. Sean McVay, just 33, is the youngest coach in Super Bowl history. In fact, Tom Brady is eight years older than McVay.
But despite a huge discrepancy in experience, there are good reasons for the young Rams being taken seriously.
The Rams are looking for the second Super Bowl win in franchise history, with the first coming in Atlanta in 2000. So you should not bet against the team by raising their second in the same city.
The defensive front four
Tom Brady may be the greatest ever, but the best player in Sunday's game will be Aaron Donald.
Brady lost in the Super Bowl twice against the New York Giants because of the pressure in the middle, and is 1-3 in Super Bowls when he was hit eight or more times. Led by Donald, the Rams have the talent in their first four to cause similar problems to the number 12.
No coordinator trains more against Brady than Rams defensive coordinator, Wade Phillips. In the AFC 2015 championship, the Denver Broncos – under Phillips' tutelage – got behind Brady like no one else since, firing four times and reaching him 17. Phillips and played historically with Belichick and Brady: the last three Phillips times faced the Patriots, their defenses gave an average of 19 points per game.
But it's not just L.A's ability to get behind the passerby who will play a determining factor on Sunday as the Rams have given up playing just 98 yards in the playoffs so far.
Donald is the best defender of Rams, but Aqib Talib is arguably the most valuable. Of the $ 221 million that the Rams spent in this off-season, no acquisition provided a better return on investment than the Talib.
The veteran defender missed the 4 to 12 week with an ankle injury but is back on the field in the playoffs and playing well, which should change the way we perceive Rams defense. With Talib, L.A.'s defense dropped 18.3 points per game, 312.4 yards per game, 209.9 yards per game, 11-13 TD interception rate and 78.4 opponents rating. Without a Talib, the Rams gave 30.8 points per game, 401.3 yards per game, 272.6 yards per game, TD 23.6 for interception and 111.6 for passingers.
The 32-year-old knows the New England scheme well after practicing against them every day as a former member of the Patriots. Talib can re-haunt his old team with a big play, but even without making a play-changing move, his ability to play in the slot and cover any of the tight ends to No. 1 receivers increases the defense ceiling of the Rams and gives Phillips flexibility as a defensive game caller.
The disappearance of Todd Gurley was greatly exaggerated.
Since 2015, Gurley has led the championship with 46 quick touchdowns. This season, including the playoffs, Gurley has 1,376 yards running, averaging five yards per carry and rumbled by 19 rushed TDs. The Rams are 11-0 when Gurley gets 15 more carries this season. And not long ago the Rams attacked the Dallas Cowboys for 273 yards in the Divisional Round.
With one week goodbye after the NFC title game in which he barely touched the ball, Gurley rested. Everything he's heard in the last two weeks is how bad he's playing. He is prepared to be an angry runner on Sunday.
The Rams are likely to run him down early and often with the Lombardi Trophy at their fingertips.
To beat the Patriots, you can not win. Just ask Dee Ford and the Kansas City Chiefs.
The Rams are the least penalized NFL team this season. It is not often that Belichick faces a team that is more disciplined than he is training.
