Last week, I noted that the Colts/Vikings game was the least-conforming game of the 2016 season. Here’s what I wrote then:
The Colts were 0.2 points per game better than average last year, as measured by the Simple Rating System (which takes the points scored and allowed in each game, and adjusts for opponent strength and home field advantage).
The Vikings were 0.9. points per game better than average in 2016, and hosted the Colts in week 15. Given those facts, we would expect Minnesota to have won by 3.7 points. Instead, Indianapolis upset the Vikings, 34-6, beating the expected line by 31.7 points. That was the least-conforming game of 2016.
Well, it wasn’t just the SRS that found that game to be pretty odd. Our friends in the desert expected the Vikings to win by 5 points, which means the Colts covered the point spread by a whopping 33 points. Two weeks earlier, Indianapolis was actually an underdog in a Monday Night Football game that you would have had to been an idiot to attend in person. The Colts were 1-point underdogs, but won by 31 points, giving Indianapolis a 32-point cover. Those were two of the three biggest covers of the year, with the Eagles 34-3 win over Pittsburgh as 3.5 point underdogs (+34.5) being the biggest cover of 2016.
At Pro-Football-Reference.com, we have points spread data going back to 1978. Below are the biggest covers in history:
