If your only argument against my point is that I haven't provided a falsifiable model for predicting success and failure in the NFL, your argument is pretty weak. There isn't such a model, nor has there ever been. Human action simply isn't that predictable, hence why economics is known as the dismal science. If there were such a model, it would likely become as obsolete as the Philips Curve once anyone tried to implement it. Empirically speaking, what we have is a 7 game losing streak--a fairly rare occurrence in the NFL regardless of a team's talent level. Therefore, we can infer the blame--at least in part--falls on the coaching staff. It's okay to admit he's at fault. In fact, admitting fault is how we grow. Believe it or not, you can admit he's at fault without believing he should be fired. The two premises aren't mutually exclusive.
Regarding your "emotion" claim, lolololololololol. Jauron and Kotite evoke no feeling from me. If I seem emotional, it's only because you're projecting. Seriously, bruh, it's possible for a person to offer rebuttal to your points without being emotional or illogical or otherwise intellectually impaired. There is such a thing as honest disagreement.
