2020 Super Bowl rosters: Every starter and key role players for Chiefs vs. 49ers, plus much more

Super Bowl LIV is underway and the first half of this game was just as close as anticipated. The participants in this year's title game have two of the strongest rosters in the league, but that's not the only reason why the Kansas City Chiefs and San Francisco 49ers are battling for the Lombardi Trophy. Andy Reid (Chiefs) and Kyle Shanahan (49ers) deserve the credit as the designers of these offenses.

Reid's pursuit of a Lombardi Trophy makes him one of the biggest sentimental favorites in Super Bowl history, after he led the Philadelphia Eagles to the big game 15 years ago. But one thing has eluded Reid during his 21 years as an NFL head coach is winning a ring. Shanahan is trying to join his father as the only father/son duo in NFL history to win Super Bowls as head coaches. His father, of course, was the legendary Mike Shanahan, who found success with the Denver Broncos.

Super Bowl LIV also includes an intriguing quarterback matchup between Patrick Mahomes and Jimmy Garoppolo. While Mahomes, last year's league MVP, is looking to join Ben Roethlisberger and Tom Brady as the only quarterbacks to hoist a Lombardi Trophy before their 25th birthday, Garoppolo, who won two Super Bowls as Brady's backup in New England, is looking to join Joe Montana and Steve Young as starting quarterbacks who have guided the 49ers to a Super Bowl victory.

Here's everything else we'll be keeping an eye on:

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.

San Francisco 49ers

With running back Matt Breida leaving Sunday's NFC Championship Game with a shoulder injury, fellow running back Raheem Mostert enjoyed a record-setting day. A former undrafted rookie who was cut by six teams before joining the 49ers, Mostert rushed for a franchise record 220 yards and four touchdowns in San Francisco's 37-20 win over the Packers. With Mostert running at will against Green Bay's defense, Garoppolo attempted just eight passes as the 49ers ran the ball a whopping 42 times for 285 yards.

Defensively, the 49ers boast pass rusher Nick Bosa, the NFL's reigning Rookie of the Year. San Francisco's defense also includes veteran cornerback Richard Sherman, whose interception late in the NFC Championship Game sealed his third trip to the Super Bowl. Led by Bosa and Sherman, the 49ers' defense allowed just 30 points while forcing five turnovers in their playoff wins over the Vikings and Packers.

Here's a look at the rest of the 49ers' starting lineup, along with several key reserves who have made an impact this season:

Kansas City Chiefs

Led by Mahomes, the Chiefs became the first team in NFL history to overcome 10-0 deficits in consecutive weeks in the playoffs. Mahomes has enjoyed a stellar postseason to this point, completing 65.7% of his passes with eight touchdowns and no interceptions. One of his favorite targets over the past two years has been All-Pro tight end Travis Kelce, who caught three touchdown passes in the Chiefs' divisional round victory over the Texans.

Kansas City's defense, one of the league's worst run defenses 10 weeks into the regular season, has seen vast improvement over the team's eight-game winning streak. Led by safety Tyrann Mathieu and linemen Frank Clark and Chris Jones, the Chiefs held Titans running back Derrick Henry to just 69 yards rushing in Kansas City's 35-24 victory in the AFC Championship Game.

Here's the rest of the Chiefs' starting lineup on both sides of the ball, as well as key backups and other players who have seen action in the postseason:
