There is no Oracle who contemplates matchups and decides on the odds after a long period of meditation. I can tell where the odds and lines don’t come from Buddhist Monks in the Himalayas sent via carrier pigeon to Las Vegas, Nevada and Atlantic City, NJ. It is funny sometimes how the betting odds work for the underdog in the NBA or NHL, MLB or college football matchup. Sure it is mystifying that the Tennesee Titans are listed at -7 over the Buffalo Bills with the game in Bills country, Orchard Park, NY. As a gambler, you have probably wondered from time to time where the odds and lines come from at casinos and online sportsbooks.
