Easy there, Hoss!
What is the reality of the McD era?
Well, we know for sure it was a 5 Alarm Tire Fire BEFORE he got here! But like the OP, my ONLY metric is equivalent to his “signature win” criteria. I don’t give a fiddler’s fart about rolling the league stiffs in a given year. I want to know and have tracked for every millennial year, what have the Bills accomplished against Playoff Teams of the SAME year? I don’t care, T this juncture, about winning by 1 point or 30, by fluke, by determination, by great plays and bad plays.
Simply, what happened? The answer is, PRE McD, they were awful, winning at a 19-78 pace or 24%... about 9% on the Road. Terrible, right?
And now your ‘miraculous HC’?
Bills under McDermott v.s. Same Year Playoff Teams
2017 = 2-4
2018 = 0-7
2019 = 1- 4
2020 = 0-2 ?
TOTAL = 3 - 17 OR 20%
They are WORSE!
There are at least 2 other Likely Playoff Bound teams coming up, not counting N.E. - Seattle & the Steelers. Keep track.
NADA has been markedly improved as yet.
And blowout wins over the Trevor Lawrence candidates, never count!
