Is there a harder award to predict in football? It would have been impossible to predict who would win the award this time last year, as eventual winner Bruce Arians wasn’t even a head coach until October. Of course, that doesn’t excuse my terrible selection. As I said last year, predicting in the pre-season which coach will ultimately win the award is so difficult that Vegas doesn’t even offer odds on the event. For reference, below is a look at every coach to ever be selected by the Associated Press as NFL Head Coach of the Year: for what it’s worth, Arians saw the biggest increase in winning percentage of any COTY winner. Arians also broke a tenure deadlock: until last season, both 1st and 2nd-year coaches had won the award 15 times, but now first-year head coaches are in the lead having won the award 16 out of 57 times (28%).
