After watching Understanding Torques and Forces in the Golf Swing (https://vimeo.Com/ondemand/forcesandtorque), I started out to ponder what become going on with a number of the gamers on Tour that had the steepest assault angles. As Dr. MacKenzie notes in Understanding Torques and Forces, out of the 30 Tour winners he studied, handiest 1 of them did now not get the Center of Mass below the Net Force. Dr. MacKenzie wasn?T telling who that turned into, but did word that he changed into called a terrible driving force of the ball (I assume I realize who it's miles).
I desired to peer the commonalities of those steep assault perspective players and I started out to look a not unusual topic. One that didn?T marvel me after looking the video and the alternative that I didn?T think about, however made sense.
One player I checked out was Trevor Immelman. Golfers rave approximately his swing, however his ballstriking has been very poor for pretty a while. Look at the YouTube remarks and maximum golfers assume he has a super swing.
However, here are his key radar metrics which are the nice indicators of assault perspective:
Carry Efficiency is Carry Distance divided with the aid of Club Speed. Immelman throughout these years has been both ultimate or 2d to final in launch attitude and is one of the worst on Tour in Carry Efficiency. I even have a proprietary algorithm to assignment attack angle and from 2012 to 2015 his Attack Angle projected at -7 stages with the driving force in competition.

This is some thing that Dr. MacKenzie and Joe Mayo noted in their video; a player can flatten out the shaft in the downswing and now not appearance ?Over the top?, but if their palms are touring at the identical angle as the club head is travelling, they're not getting the Center of Mass underneath the Net Force. This manner a steep assault attitude and leftward path.
One issue I noticed about Immelman?S swing turned into the clubface angle. Immelman came at the beginning from the Leadbetter faculty of teaching which wanted the toe straight up at P2 (whilst the shaft is parallel to the ground within the takeaway)
That makes for an open clubface on the pinnacle. While I don?T usually consider the idea that slicers slice the ball because of an open face, I do believe that there are many golfers so as to react to an open clubface through swinging extra left like Immelman does to get the ball to begin on-line.
Here's every other steep attack attitude player in Ricky Barnes. Here?S Barnes? Radar metrics through the years:
Again, one of the lowest Launch Angles and Carry Efficiencies on Tour. His projected assault angle the use of my algorithm in 2016 turned into at -eight.Four degrees.
What I see is the identical symptoms?.He flattens the shaft out inside the downswing, but it?S basically on the equal perspective as his palms are visiting.

And like Immelman, we see the same problem of the clubface being open within the backswing.
I know other instructors have been teaching the dangers of an open clubface in the golf swing and have also been teaching how it forces steep attack angles with Tour level talent for the reasons I had mentioned. I think for the average reader that is not in the know, they can see that an open clubface in the backswing presents many problems which includes hitting the ball lower than having a closed club face because the attack angle can steepen.
