This sounds an awful lot like coaches complaining that they don’t want to learn how to do new things. The Norv Turner section, for example: What’s actually stopping him from pointing out the things he used to point out? Can he not explain the context on the play anyway?
Also: it’s not hard to avoid information overload if you tell players what to study. If you don’t want a wide receiver to watch five years of film on a skinny post, then tell him not to do that.
