It's not all or nothing. The bottom line is that dumbing down things that you have nor real understanding of in the first place posits nothing. A team changes OC and they win the Super Bowl so obviously that means it's the playcalling? Really? You find merit in that line of thinking? People dumb down an OC's responsibilities down to DERP PLAYCALLING! and they do it over and over and over and over and over again. When I do read stuff from people that I respect their acumen like Sturm and Vela I never see the DERP PLAYCALLING routine. They talk about play execution and formation trends. Actual specific observations. What a novel idea. Again I go back to dumbing things down that you do not grasp in the first place posits nothing.
