Yes, interesting fact, no undefeated team has ever won the SuperBowl in modern times. The last team to get to SuperBowl undefeated was the 2007 Patriots. They lost to NY Giants in the championship.

It’s very common if a team is undefeated and has already won enough to lock in there playoff seed and home field advantage , they will rest there first string players and loose last couple games of season since there’s nothing more to gain.
