I know many guys who have been playing golf for decades. These same guys have not improved beyond a certain hcp index, and if anything, they're adding strokes to their hcp. However, they continue to watch other online "teaching pro's" who incorrectly analyze tour pro swing movements, then run out to the range and beat 800 balls only to find nothing improved.
Just the other day a guy sent me a video of Xander Schauffele's swing for which the online pro (reviewer) said Xander loads onto his right side at the top. Upon watching the video it's clear at least 70% of his weight has moved onto his lead leg at the top because his lead knee is bent fairly significantly, and his tailbone has moved towards the target...not as much as Hogan...but about 2 inches. So how on Earth could his weight be "loaded on his trail side"? A simple check would be to see if Xander could easily lift his lead leg off the ground at the top. Based on his position there's zero chance he could lift his left foot off the ground.
Thus, now my buddy is working on getting his weight over his trail knee at the top...and...keeping his right foot straight...wow. The result will be 10 more years of the same exact handicap, same inconsistency, and same exact chain reaction of "fixes" that never materialize into any improvement.
It's amazing how even so-called online "pro's" see "what they want to see" as being the "proper" movement in the golf swing despite the fact that the video evidence is clear that a majority of pro swings are very close to, or S&T swings. Worse, folks who watch these videos believe the online pro's "observations" despite the obvious inconsistencies between what the online pro says the tour pro is doing vs. what the tour is actually doing.
LOL!! I suppose there are multiple ways to get "loaded", with one oftentimes leading to the other!!
