See this thread posted in Jeffy's forum jeffygolf.com/showthread.php?378-An-interesting-video-lesson-by-KelvinHere is KM's video presentation Kelvin irrationally claims that the golfer is making a mistake by having his left antecubital fossa face the ball-target line at address. He calls this an unstable position and he believes that it causally related to his right wrist straightening after impact. I have no idea why he believes that it is more unstable than the usual scenario where the antecubital fossa faces slightly more away from the target at address and at impact. I also cannot see any causal connection between the left arm's degree of external rotation at address/impact and the degree of right wrist straightening. I think that the golfer has a lot of right wrist straightening through impact - because he runs-out-of-right arm. At 6:50 minutes, a DTL view shows that he stands up at impact and that his pelvis/upper torso is too square at impact and he therefore cannot get his right shoulder far enough downplane by impact to prevent a running-out-of-right arm scenario. It is also ironic that he uses Dustin Johnson as a comparison - considering the fact that DJ also has his antecubital fossa facing the ball-target line at address and at impact. There is nothing unstable about DJ's impact position as a result of this choice of left antecubital fossa alignment at address/impact. Tim Clark is another golfer who adopts this type of left antecubital fossa alignment. Jeff.

I don't believe that there is any rule as to whether the antecubital fossa should i) face towards the ball-target line or ii) more away from the target - other than the general observation that golfers who adopt a weak left hand grip often adopt choice number i) and golfers who adopt a strong left hand grip usually adopt choice ii); and that these individual golfer choices are based on practical human biomechanics.

nmg,
If you believe that adopting a left arm alignment at address, where the left humerus is more internally rotated at address, leads to less likelihood of left arm injury in a full golf swing - then I would like to see you present an explanation.
Regarding your father, I have no idea where he experiences pain and I have not examined his swing mechanics, so I cannot rationally comment on his particular/individual swing scenario.
Jeff.

nmg,
I suspect that if a golfer can maintain a straight left arm throughout the swing, then the likelihood of left elbow injury is small - irrespective of the position of the antecubital fossa at address. I suspect that left elbow injury is much more likely in golfers who chicken-wing their left arm during their swing action (as can be seen in Jack Kuykendall's non-traditional swing action).
Jeff.
