In 2015, when Bill Belichick was at the height of his powers and New England’s season seemingly began in the AFC championship game, the Patriots went on a coin-flip hot streak.
They won 19 out of 25 times.
The odds of such a thing, the Boston Globe computed, was 0.0073, or less than three quarters of 1%. It appeared to defy probability. National Public Radio even did a segment on it.
There was no secret, of course. It was luck and, to briefly get into the mathematical weeds, actually not that improbable (more like a 20% possibility).
