MTV's Head bangers ball
 

to be perfectly clear no matter how many pros drop their head in the downswing, and no matter how many so-called golf swing experts think it is an asset and will tell you 'it's ok look the pros do it!' it is ALWAYS a fault!!! You will hit the ball better by keeping your head in the same place guaranteed, nuff said. Sorry brianid you are very mistaken, tiger has anything but an uncocked left wrist at setup in reality he has the complete opposite, his wrists In a cocked position because of his low hands setup has both Wrists in a cocked position and both arms straight another common fault seen on the PGA tour, common as the head drop neither of these things are helping there golf swings, rather they play well despite these faults because of RAW TALENT AND BALL- HITTING SKILL just as players in previous eras were sliding the knees all around trying to get "leg Drive" this wasn't helping them, they were playing well despite it.

I believe these faults also go hand-in-hand(no pun intended) with the current fad of swinging the hands way left, which requires a cocked left wrist through impact in order for the sweetspot to come anywhere close to tracing the plane line. If the left wrist is properly level at impact, swinging way left means a bent plane line. :(

How is this different from all the trigger delay here?

Trigger delay? :confused1

Ok...you don't like that description....

How is what you said different that what is going on in the picture of Bently J Doyle? Both have the left wrist cocked for a long time...I don't care about debating an understanding of terms....I'm more interested in how what you described as swinging a cocked left wrist to the left and whatever you want to describe Doyle doing here as a different....

Seems to me what Doyle is doing.... what Eldirk is doing.... and what you described are very similar....

If you'd like to explain Trigger Delay to me and then tell me how this other stuff works....I'm ready to learn.

Bucket, the pivots are the biggest differences. Tiger is way more left than Doyle with almost the same trigger delay/lean/lag/angle/retained wristcock or ulnar deviation. Whichever is now acceptable.

Witcha! But does that make it all better?

Is it really trigger delay, or just the left arm-shaft angle being that way right from the start (i.e., setup)?

Are we sure it's in c0cked state at setup, or is it just that the grip/shaft is more across his left hand (more PA3 angle)? IMO, its unc0cked at setup, but he has huge acute angle between his left arm and shaft. That's what I call "built-in lag". At impact, his left wrist is level, so he has to make his left hand lower; hence the head drop.

Plus, isn't the head drop just a consequence of starting the DS with a lower body/hips move, which moves the left hip nearer the target, weight more on left foot/leg, and with intention of keeping the upper body cog or head somewhat fixed, your head has to move down or spine tilt away from target, hence move your head down?

It doesn't by itself make it better or worse. Just different. There is no universal correct amount of lean or trigger delay. There are SO many factors involved.......
When one major champion has tons of shaft lean and "rhythm" ala Trevino, and the other has virtually zero ala Nicklaus, the fun is to figure out how and why they both work. It is impossible to teach a specific amount of lag or lean, for example, to the masses without ruining someone along the way.
