I know that was one of Hogan's major changes coming back to competitive golf after the service. He went from a "long thumb" to a modified "short thumb". He said the "long thumb" let the club drop down too far at the top of his backswing and it was tough to get the timing correct.

The rule of "thumb" is long thumb = longer backswing, short thumb = shorter backswing.
I would like to hear what TGM has to say about it too!
