## Predicting the Super Bowl

by

It is probably bad form to start off with a disclaimer, but here it goes anyways:  I don’t follow the NFL.  I am aware that the Steelers and the Cardinals are in the Super Bowl, and I am aware that the Cardinals are not from St. Louis, where the Rams play now that they’ve left LA, and the Raiders aren’t in LA anymore either.  (Nor are the Chargers.)  But I’d be hard pressed to name any of the current players for the Steelers or Cardinals, so any opinion I might have to offer about the game will be based on other data.

I am going to a Super Bowl party this afternoon, and there is likely to be discussion (or perhaps -ahem- a “party game” with prizes and such) focused on the final score of the contest.

What strategy would one employ in order to be most likely to predict the final outcome?

After perusing the final scores of 12,595 NFL games (from 1922 to the present), I’ve found a few patterns:

• The most frequently occurring scores for an individual team are:
• 17 points  (7.2% of all scores),
• 14 (6.3%),
• 7 (6.1%),
• 24 (6.0%), and
• 10 (5.9%).
• The least frequently occurring total scores [under 20]  are:
• 1 point (which never can happen under NFL rules),
• 4 points (which happened once:  Racine 10, Chicago 4, on November 25, 1923),
• 5 points (18 times in NFL history),
• 2 points (31 times), and
• 8 points (36 times)
• It is possible for a team to score exactly 1 point under NCAA Football rules, but I haven’t had a chance to search through that ocean of data to see if it has ever happened.  [If a team is attempting a PAT, and a safety occurs, the defending team gets 1 point under the NCAA rulebook [see page FR-108.]
• The most frequently occurring final scores are:
• 20 – 17 (211 times),
• 17-14 (162 times),
• 27-24 (153 times),
• 13-10 (141 times), and
• 24-17 (125 times).
• Modulo 10, the most frequently occurring team scores are:
• 0 (19.3%),
• 7 (19.1%),
• 4 (15.1%), and
• 3 (12.3%);
• The least frequently occurring team score modulo ten is 2 (3.1%).
• Modulo 10, the most frequently occurring pairs of scores are:
• {0,7} (8.1% of all games), followed by
• {4,7} (6.8%),
• {0,3} (5.8%),
• {0,4} (5.2%), and
• {3,7} (4.5%).
• The least likely combinations modulo 10 are:
• {2,2} (0.024% = 3 times in NFL history), followed by
• {9,9} (0.10%),
• {5, 5} (0.14%),
• {5, 9} (0.25%), and
• {2, 8} (0.26%)
