BetMGM bonus code WRAL158: Earn $158 bonus for SF-KC with $5 bet

Super Bowl LVIII kicks off Sunday from Las Vegas, where the 49ers and Chiefs will square off for the NFL's ultimate crown. San Francisco is a two-point favorite on BetMGM, while the over/under sits at 47.5 points. Patrick Mahomes, Travis Kelce, and the rest of the Chiefs are aiming for their third Super Bowl victory in five seasons, while Brock Purdy, Christian McCaffrey, and the Niners hope to earn the franchise's first Lombardi Trophy since the 1994-95 season.

There are a few Super Bowl props I'd consider throwing bonus bets on. First, there's a lot of value with Brock Purdy at +100 odds to throw under 1.5 touchdown passes. Although Purdy's led an elite offense with a top-five air attack, Kansas City has arguably the NFL's best pass defense. Through 20 weeks, only four QBs have thrown for 2+ touchdowns against the Chiefs, and none since Week 13.

I'm also siding toward under 47.5 points (-110). Every Chiefs game has been lower-scoring than expected, with their defense serving as the primary catalyst. The Niners have also started their two playoff games with just seven points in the first half, relying on second-half comebacks to save them. Despite the offensive talent on both sides, I don't think we'll see a shootout on Sunday.
