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.

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.
