Stationary Head - To be or not to be

Is that the key reason tho?

The shoulder/chin 'collision' forces one to move the entire body away from the target and/or dip to continue the backswing shoulder turn - a common problem. Chin position can have a huge impact.

A swivel of the chin can help prevent this, as well as act as a 'backstop' for ensuring a complete turn.

Flexibility and/or lack thereof, is certainly a factor as well.

I don't entirely know....but something's telling me there must be reasons more "key" than that.

Seems those things could influence it...(although I'm a pretty flexible guy)...

I think there must be other factors.

I'm thinkin anatomy. (for one anyway)
