The Baltimore Ravens had the NFL’s best record in the regular season (13-4) and quarterback Lamar Jackson, 27, looks set to win the season MVP award for a second time.
But despite Baltimore’s commanding wins over the San Francisco 49ers and Miami Dolphins in December, the 49ers have been favourites to win Super Bowl 58 since late November because of their star-studded roster, with versatile running back Christian McCaffrey their biggest threat.
One of the Super Bowl favourites throughout the last few years, the Buffalo Bills seemed to be out of contention in late November but won their last five games to snatch the AFC East division title from Miami.
The Dallas Cowboys were one of three teams with a 12-5 record, have won their past 16 games at home and, if they win on Sunday, will have home advantage for at least the first two rounds.
The Kansas City Chiefs, who beat Philadelphia in a Super Bowl epic last season, were 11-6 and have the opportunity to cement their dynasty with a third NFL title in five years.
And despite limping into the post-season with five defeats from their last six games, the Philadelphia Eagles are still among the favourites to reach Vegas.
