I agree with one of the guy's premises. I agree people need to pay their dues and the younger generation (which I would probably be put into) can be unappreciative. I also agree that it is a poeple's game and they the people aspect should not be ignored. I totally agree with him on those points but he conflates that with analytics and analysts where he sounds like the old man shaking his fists at the sky.
Computer, analysts, and analytics should be a tool to help, not a crutch and should not be shunned like he is implying. "How can a computer tell you whether it was raining or whether the wind was blowing?" Dude WTF? Have you never heard of the weather channel? He is basically saying "In my day we had to build the field from scratch in the snow uphill both ways and line it." That's great but what does that have to do with someone helping a headcoach do a breakdown or the analytics saying this team is terrible at defending a screen pass?
If anything, the Belichick's and Saban's of the world who went through what this guy went through but still embrace and take advantage of what we have now should be the model. His whole "back in my day" is the opposite side of the same unappreciative "why am I not a coordinator in the NFL" coin. He's unappreciative of the advancements and technology in the game today.
