Here is another sequence from the Side....I am trying to get Chris to use extensor action to maintain a straight left arm on his backswing. This is something very hard for him to correct. I told him today to do acquired motion swings and film those. Any comments would be helpful on things to correct and in the order they should be attacked. Thanks all.

Really nice sequence photos because they make obvious so many possible solutions.
I won’t go into everything, but I’d like to say that if he isn’t a very low handicap player now, he’s only a few minor adjustments from becoming one.
Start-up, Backswing, Downswing, Release, Impact, have issues which stem from Zone 1. The most problematic issue is that he creates a swing pattern to compensate for the lack of good impact geometry. He ran out of right arm before impact because he lacks pivot lag.
If you look at his shoulders and hips at his current impact geometry, that’s approximately where they belong during the start of release. Zone 1 virtually stops after Startdown. He hops onto his Left Leg and throws the Clubhead at the Ball and his experience allows him to fight the swing well enough to provide a good imitation.
If his Zone 1 issues can be resolved, then most everything else will change to comply with his new impact geometry. Approximately frame #71 illustrates the Geometry of Impact of his Shoulders. Frame #74 his Hips but they’ve swayed 6 inches Left because he jumped to his Left Foot at Startdown.
His Right Forearm misalignments illustrated from Frame #66 to Frame #69 should almost entirely self-correct as he acquires a straight line Deliver Path.

Tell him to get his shoulders as in Frame #71 but Square to the Target and that's where they belong Impact. Adjust Hips more open and closer to Center. Teach impact fix alignments for Zone 1 not just Zone 2.

Currently, if he's on an uphill lie with the Ball below his feet, I don't think I could watch.
