There have even been some on Cougarboard at times who tried to assure us that Tuiaki's D was fundamentally sound and that there was nothing at all wrong with his scheme, if only players would execute it better. He hears too much of that nonsense and buys into it, no amount of natural talent can overcome that millstone. Be very wary of those charlatans.
