As kickoff approached Sunday, sportsbooks were almost unanimously rooting for the favored San Francisco 49ers to win in a low-scoring Super Bowl.

Late in the fourth quarter, everything was going the books' way. Then, the game went into overtime.

The underdog Kansas City Chiefs rallied from behind in overtime to pull out a 25-22 win behind another Super Bowl MVP performance from quarterback Patrick Mahomes, resulting in a big swing in favor of the betting public.

The Chiefs covered the spread as 2-point underdogs, and the game went over the consensus closing total of 46.5. Both were good results for the betting public, as was overtime.
