How games at these numbers have gone

  • The key number. 3.5 sits half a point past 3, one of the margins games actually land on. That hook is most of what you are paying for or getting here.
  • Spread 3.5 โ€” the 3-4 point band. In 1,756 games since 1999 the favorite covered 48.5% of the time โ€” a coin flip once the 95% range (46.2โ€“50.9%) is taken into account.
  • Total 40.5 โ€” spread in the 3-7 point band. Games with a spread this size went over 49.5% of the time across 3,584 of them.
