Lindsey and Kevin,the human body is not a machine and they are not all created equal.There are some things that a contortionist do that does not make sense to me either.I read somewhere Sergio can do things with his wrist that you wouldn't believe and it's the reason he can achieve the amount of accumulator lag he has.
There is no question Sergio has tremendous rotation to go along with his arm and hand drop.Freeze frame him at impact and you will see how incredibly open he is.The less flexible may indeed need to curb rotation in order the get more vertical drop of the arms and hands.Can this work?Probably could I guess but it's not Sergio.
As for personal attacks,I doubt it will be tolerated from posters but in a closed forum,it is acceptable from certain people which I understand.We are grown adults,however.This is just a discussion on golf.There are more serious things in life.
At no point have I attacked anyone personally on this forum, so if you're pointing to me, I will challenge that all day long. Please, go back and review my posts in this thread, as you will find nothing that resembles hostility or malintent. As far as more important things than golf, I am fully aware of that.
Again, I was contesting the statement that the hands, to quote, "they are pulled down by hip rotation". You said you took that from what Sergio had stated, so in fact I was not even questioning your statement, but Sergio's.
Probably a more accurate statement would be that the hands are pulled "around" by hip rotation.
Yes, sergio has hip rotation, but I still see in no way how that creates or assist the vertical drop of his hands and arms. In fact, it is due to his high flexibility that his hands are not forced horizontally by that rotation.
