How games at these numbers have gone
- The key number. 5.5 sits half a point short of 6, one of the margins games actually land on. That hook is most of what you are paying for or getting here.
- Spread 5.5 — the 4-6 point band. In 1,063 games since 1999 the favorite covered 49.2% of the time — a coin flip once the 95% range (46.2–52.2%) is taken into account.
- Total 55.5 — 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.
