An interesting read, but any premise that rests on the idea that MM went from being an universally acknowledged passing innovator/QBs guru to "stuck in a 1973" in just a few short years is suspect to me. This is a coach who designed schemes that the whole NFL copied just a few years ago- now the problem with him is that he's a dinosaur from the 70s? Hmm...
It's fair to criticize MM's scheme, but any criticism that doesn't start with our lack of proper personnel in the WR/TE corps cannot properly diagnose the problem.
The culmination of inexperience, injuries and lack of talented depth across the board at the WR/TE spots the last year and a half has to be the primary acknowledgement of any accurate assessment of the problem. This is a problem that was bad enough that even TT came out of his cave to use FAgency to address it (Cook this summer, JJ last summer).
It's personnel issues that have undermined MM's scheme. This is the primary assumption, imo. Then you move on to scheme from there.
This understanding makes the criticism of MM's schemes fundamentally different, because it then becomes "why hasn't MM adjusted his schemes to account for lack of the proper personnel?", which is very different from: "MMs scheme is essentially unsound".
This is an important distinction- and it's one that, right or wrong, accounts for MM's stubbornness in addressing the problems (it's also a distintion that, if one makes it, saves one from making shaky premises like "MM is stuck in the 1970s").
