Home teams who have allowed more than 20 points over their last two games are 35-13-1 72.9% (7-14-1 if not (11-18-2 from the 46-31-3)). That would rule out NE this week and leave KC, St. Louis and Philadelphia. By the way, teams allowing 20 or less points over the last two games went 0-3 last week - playing against Green Bay, Dallas and Baltimore.
In other words, if they allowed 20 points or less over their last two games they were in a play against situation because they peaked too early.

Why is 20 the "magic" number?
I'll tell you why, because backtesting determined that it would spit out the best ATS data.
It doesn't make sense that teams allowing more points would do better than teams allowing less, leaving one to conclude that this is the result of randomness.
How far back does it go?
I will get the data for you for the 20 years prior to that and I bet you dollars to doughnuts it's around 50/50 if not worse.
