Yes, completely my opinion. I have not heard him or anyone else say that he had a physical issue this weekend. My strong belief is that with all golfers - esp professionals, when they have variations in their swing it is due in a large part to something going on physically (unless they are going through a purposeful swing change.) The body is a master at compensation due to tightness or pain- even when you are not consciously aware of it. With most golf discussions it is an elephant in the room that is ignored. It may not be the only reason for swing variations but I promise you it plays some role.
The better your swing- or the better player you are - the more you can get away with any physical issue but it factors into the mix.
I've never talked about this before....but it has crossed my mind. I think you have a point. (in general)
As for Tiger and all this.....still not sure about Tiger but it (the physical) very well could have been a contributing factor. Who really knows.
....
But ya....everyone's experienced it before....."something's different today"....."something's on"....."something's off".....
Most people just chalk it up to some kind of mystery. "That's golf."
I can see your point and I don't see why it wouldn't be a possibility.
BTW I don't care....I'm open to talk about this. (I know what you mean about people ignoring things like this)
There also is the mental side of things....what's "on your plate"......the anxiety issue....etc. Cause I know when my allergies are bad or I'm "off" in some other way (and the anxiety is up- cause that's the real issue if you ask me...that and physical fatigue)....man sometimes I feel like I can't hit a shot to save my life. "Out of sync." But you just manage I guess. And forget control....manage.
And of course like you said good mechanics will get you through a lot of the bad times.....but if you've got something on your plate you've got something on your plate.
Would be cool to ask a guy like Hogan or Moe Norman if in their prime they had noticeably off days......and how off were they?.....or did they more or less flush it all the time?.....or were their misses just better?.....or did they know how to get it back when it went bad?.......or did they just manage themselves and their games so well that people thought they were "on" all the time?
Hmmmm....interesting topic.
