Sunday NFL betting preview

New England engineered a remarkable turnaround under head coach Mike Vrabel this season, going 14-3 after going 4-13 last year. The Patriots have added wins over the Chargers and Texans in the playoffs, and they are 4.5-point road favorites against the Broncos in the Sunday NFL odds at BetMGM. Denver is a home underdog due to starting quarterback Bo Nix going down with an ankle injury last week against Buffalo, leaving Jarrett Stidham as the inexperienced starter for the AFC Championship. 

The NFC Championship kicks off at 6:30 p.m. ET, as the top-seeded Seahawks host the fifth-seeded Rams. Seattle and Los Angeles split their regular-season series, with those games being decided by a combined three points. The Seahawks are riding an eight-game winning streak, and they are 2.5-point favorites for this rubber match. Bet on the NFL at BetMGM to get bonus bets:
