Since the Napier-style is open and unadorned with "sugarcoats" that's unusual in these times taught by the advertising industries which thrives on lies, lies that they are not concerned about fulfilling - so today's kids are taken aback. They suspect honesty, not deception. They embrace the sham scene. That is only rescued by the fact that football is a "feats-on-the-ground" reality. Hopefully, that's when buying into the "Napier way" shows its superiority, by producing good exciting football in the eyes of fans but pundits too.
Vince Lombardi would have a hell of a time recruiting modernity's players.
