Are we talking "Missing Piece" here?

The Reverse Hip Turn is essentially a lateral Hip Slide that tranfers the weight to the Left Foot during the Backstroke. This certainly is a major feature of the "Missing Piece" as described by V.J. Trolio in his book The Final Missing Piece of Ben Hogan's Secret Puzzle.

However, V.J. describes the first part of the Hogan Backstroke as a "bump" (a slight lateral Hip Shift) to the right (away from the target). This typically would not be the case in a pure Reverse Hip Turn, particularly when employed with the Short Shots (its normal use).

By the way, the Lee Trevino application was restricted to short Pitch Shots or other specialty shots (such as buried Bunker Shots or high-spin Punch Shots). He did not use the Reverse Hip Turn as part of his normal Stroke Pattern.
