Hogan question

[ColtsFan]

In reading 5 Lessons I was wondering if anyone could explain something. Hogan said that any use of the hands to square the club is pure folly and a timing nightmare essentially . But then he says that you need to supinate your hands/wrists just prior to impact.

Dont you need to time the supination so your wrist so it is bowed/flat at impact? Especially in his case where he had a cup in his left wrist at the top?

Would you guys say Hogan was TGM?

Thanks
