Ravens and 49ers, big favorites in the Finals

For their part, the Kansas City Chiefs have a 36.4 percent chance of advancing to the Super Bowl.

The most significant change occurred in the high/low which opened at 46.5 and closed at 44.5.

For the NFC Title Game, the 49ers were held at -7 all week and the FPI gives them a 74.1 percent chance of advancing.

The Detroit Lions have just a 25.9 percent chance of passing in a game whose over/under remained unchanged at 51.5.

If the 49ers and Ravens advance to the Super Bowl, it will be a revenge duel after they met in Week 16 of this season with a resounding 33-19 victory for Baltimore at Levi’s Stadium.

However, despite that history, the 49ers have the best chance of winning the Super Bowl.

San Francisco is seeking its sixth title in its history, defending champion Kansas City is seeking its fourth Lombardi Trophy while Baltimore is fighting for its third.

The Lions are one of four teams (Cleveland Browns, Houston Texans and Jacksonville Jaguars) that have never reached a Super Bowl.
