I fully accept and believe that Matt Patricia was a bad offensive coordinator.
But some of the claims here about the young offensive wizards are absolutely laughable.
Look: Sean McVay is heralded as a great offensive mind. And his teams put up massive amount of points and yards. But to portray Belichick as somehow being incapable of imagining an offense that works that way?
Please: if a defensive coach knows EXACTLY what your offense is doing, and manages to predict what your offense is doing, knows how to stop your offense-- > then that person KNOWS your offense. There is no voodoo or magic or newfangled "new" offense in any of this. Belichick knows McVay's offense backwards and forwards.
Teaching that offense is an entirely different thing, having your coaches teach it is an entirely different thing, and -- most importantly -- having a QB is the most important thing of all the important things in the history of football.
