I completely disagree with any Hogan comparison.
If you truly were a Hogan disciple, you would swing the heaviest flattest gear possible.
You would super slot the club through transition via clockwise forearm rotation so you could utilize counter clockwise forearm rotation on the downswing from the third dimension under plane. Dufner has zero of this, and it is absolutely critical to Hogan’s protocols.
Knees do not properly download to change the direction of the club, and this is one of the ways lightweight clubs contribute to the failing of this critical Hogan element.
Shaft is way too steep on the downswing coming into P3, probably off 10 to 15 degrees so there is no taking advantage of flat entry and flat lie angles through impact. Shaft is never on the chi line as the great master strikers did.
While his torso does turn level, it stalls too much therefore the right arm has to get involved prematurely to aid in squaring the clubface bringing in a significant timing element that Hogan preached of avoiding.
Hogan’s right foot would never flop over to the right at finish because he understood how ground pressures worked and why they were necessary to synchronize the pivot action. The arm structure also completely breaks down as finish which Hogan never did.
Dufner’s hands come in higher at impact raising upward a bit which is another Hogan violation and in no way does Dufner release the club left as Hogan did.
There are good reasons, very clear and understandable reasons why modern players don’t strike the ball as well as Hogan did, and many other great strikers of the past. The comparisons are silly because Hogan’s ball striking was completely on another level of proficiency than anything we see today.
The good news is that you don’t have to swing like Hogan to strike the ball on occasion very well and win golf tournaments.
If you have all day to hit 100s of golf balls and play 6 days a week, you can make a lot of things work. Timing is not a problem if you have time to time it.
Now with Sergio, there is a viable conversation and comparison. But just because a player takes the club back flat does not mean they are anywhere near implementing the key elements that made Hogan’s swing work.
