It's Super Bowl Sunday -- are you ready for some football? This year's matchup features a team that hasn't been to the Super Bowl in 18 years and another that's won five titles and lost in three other trips during that stretch.

The Patriots have won five Super Bowls and are looking for their sixth on Sunday. Several players on the Patriots will be looking for their third ring after beating the Seahawks in 2015 and the Falcons in 2017. If they win, they'll join several other Patriots from 2002-05 with three Super Bowl rings. Only one player was a part of both title stretches for the Patriots, and it just happens to be the guy who's widely considered the greatest quarterback to ever play, Tom Brady.

Super Bowl LIII kicks off at 6:30 p.m. ET in Atlanta and it will air on CBS and streamed here on CBSSports.com and the CBS Sports App for free on most connected devices

In order to get that sixth ring, Brady and his team will have to get past the upstart Rams, a team that heading nowhere in 2016 before hiring the youngest coach ever in Sean McVay. Two years later, the Rams are in the Super Bowl and looking like they have the potential to one day been seen as a dynasty of their own. Taking the first step on that path means beating the Goliath of the NFL: Bill Belichick's Patriots.

As we prepare for this year's fight for the Lombardi Trophy, here's a rundown of each team's rosters, starters and key players.

Los Angeles Rams

At the center of the offense for much of an MVP-caliber season, Todd Gurley was curiously limited in the Rams' NFC Championship win over the Saints, taking just four carries and spending almost the entire third quarter on the sideline. That was despite a 115-yard outing in the Divisional Round. Even so, quarterback Jared Goff probably remains the most vital to Sean McVay's offense, overcoming a shaky start to lead L.A. back in the Superdome and outplay Drew Brees down the stretch.

In addition to Goff and Gurley, here's the rest of the Rams' starting lineup on both sides of the ball, as well as key backups and other players who have seen action in the postseason:

New England Patriots

There's no one more famous -- or polarizing -- than the Patriots' signal-caller, Tom Brady. Controversies have kept the Patriots' critics alive for years, but that hasn't stopped the 41-year-old all-star from racking up title after title. Going for ring No. 6 after a runner-up finish against the Philadelphia Eagles in Super Bowl LII, Brady has already rewritten the record books and enters this year's culminating showcase with a familiar supporting cast -- one that's starred Julian Edelman and Rob Gronkowski for years.
