Thanks for pointing these things out to me Tom! Very very very helpful
I think the power coming from the legs and hips, as well as the wide stance and even foot position, comes from my background as a hockey player but I should do my best to keep my hockey shot and golf swing separate. I see what you mean about the stance, leg movement and over swing all contributing to the knee issue.
I'm going to spend time on the range tomorrow to work on the angles and distance of my feet during stance and focus more on my shoulder turn while reducing leg/hip turn.
And on the point about the individual golf swing, I like your point and I guess I should just go with my natural swing while still sticking to the fundamentals--I also kind of like the idea that it's my swing and no one else's.
Your pointers are definitely going to help my game and my health, so cheers, I (and my knee) thank you!
