How every team that lost the Super Bowl since the 2000 regular season did the next year

The Rams were riding Sean McVay magic in 2018 when they went 13-3 and won the NFC West before the offense stalled against the Patriots in a 13-3 loss in the Super Bowl. The Rams had troubles in 2019 as they fell to 9-7 and third place in the NFC West.
