MIAMI — There are always comparisons, because when teams get this far, everyone wants to figure out what happens next.

How does this team match up with that one? How does this offense compete with this defense? To get a handle on this, games against similar opponents and systems are revealed and studied, all in hope of finding a clue to how Team A will deal with Team B.

Nothing is juicier than when a prolific offense faces a stifling defense, and Sunday’s Super Bowl 2020 is all about that, as the high-flying and high-scoring Chiefs and unyielding 49ers are set for what should be a titanic clash.

So, where do the 49ers go to get a better idea of what to expect when Kansas City quarterback Patrick Mahomes and his offensive brethren take the field? What comparable team makes sense to use as a barometer?

“They’re the fastest team by far,’’ 49ers defensive coordinator Robert Saleh said of the Chiefs. “To try to compare it to another team would not do them justice, to be honest with you. But, anytime you have speed like that, it naturally will stress the defense.”

Naturally stressing a defense is not what Saleh wants to see happen to his unit. The 49ers thus far in the playoffs have allowed only 10 points to the Vikings and 20 to the Packers. The Chiefs have overcome slow starts with fantastic finishes, scoring 51 points against the Texans and 35 against the Titans in two come-from-behind playoff victories. Mahomes is completing 65.7 percent of his passes, with eight touchdowns and no interceptions for a postseason passer rating of 131.5. He is also the Chiefs’ leading rusher with 106 yards.

“One, his mobility is unique,’’ Saleh said. “His arm strength is ridiculous. He’s very, very accurate. But, what I don’t think people give him enough credit for is that he actually plays quarterback. There’s a lot of people, there’s a lot of quarterbacks in this league that will say no to number one and then it just becomes street ball. He gets rid of the ball on time. He puts it where it needs to be. He hits a lot of throws in rhythm. And when he needs to take his shot, he knows how to buy time in the pocket and do it.” So, he’s a superstar in every way you can possibly imagine and he’s going to be tough to deal with.”

The 49ers last faced Mahomes and the Chiefs in late September 2018. Mahomes threw for 314 yards and three touchdowns, and the 49ers were unable to put up any speed bumps in a 38-27 loss.

“They’re similar,’’ Saleh said of this year’s Chiefs. “They’re very explosive. Mahomes has gotten better. They’re, at every position, it almost looks like they got their roster from the Olympic relay team and threw them all on the football field. Not to say they can’t run routes and catch either, because they can do that. They’re a special group.”

This is a better 49ers defense than last year’s, including an improved ability to harass Mahomes. The 49ers have 48 sacks this season, fueled by the work of Arik Armstead (10 sacks), Nick Bosa (9), DeForest Buckner (7.5) and Dee Ford (6.5).

“The speed that they bring to be able to run with a guy like Mahomes,’’ Saleh said, explaining why he feels his defense is better prepared for Mahomes. “But, when you have edge rushers, it speeds up the process of the quarterback, and, not that he needs speeding up, he already gets rid of it pretty quick. But it changes the game. Like I talked about last week, it unlocks the offensive line so it creates a little bit more space and it gives the guys inside more space to operate. So, having those guys out there, having them at full speed, will do nothing but help.”
