LAS VEGAS (AP) – Even the bookies are having a problem figuring out a favorite in the Super Bowl. Odds opened at pick ’em Sunday at many Las Vegas sports books, though the Kansas City Chiefs quickly moved to 1-point favorites over the San Francisco 49ers. Early bettors favored the Chiefs in a game that will almost surely set new legal betting records. The combination of an attractive matchup, close odds and the spread of legalized sports betting means hundreds of millions of dollars will exchange hands over the next two weeks.
