Gary makes good points but I see the following:
Tiger arches the wrist at impact - causing the low point to move.
Hogan is on the elbow plane on the downswing.
Tiger is on the TSP - it only appears to be on the elbow plane because he has such a significant head bob/drop.
Hogans right forearm is on plane at parallel on the downswing. Tiger's above the plane.
In essence Tiger has not mastered any of the 3 imperatives!! Can you imagine how good he would be if he did??
