Does Letting DA Go Make THIS Much Difference Or Was It Also a Function of

Sorry. Not even remotely true. That said I freely admit his tenure here was abysmal, just not top 10 historically bad.

What I think you're referring to is that CDA was the 3rd worst active coach at the beginning of this season. He was succeeded at "worstness" (chuckle) by Eberflous and Gannon to start the year (see link 1).

But there have been many worse than him throughout NFL history. I don't want to do the work to see where he actually lands but link 2 shows the worst 13, by record, in real NFL history and CDA isn't on the list.

DA is #16 all time worst by winning percentage and had the worst percentage among active coaches at the time of his firing (.329). He's worse than Romeo Crennel or Robert Saleh or June Jones. Had we not fired him he would've surely dropped further.

There have been 201 NFL head coaches all time, so he's in the bottom 8%

Raheem Morris is the current active "leader" with .386 but he's got a winning record this year (for now lol).
