Creating some motion to get motion started has long been a factor of great players. Nicklaus cocked his head. Snead and Player both gave the right knee a kick forwards.There are numerous ways to get some resistance into the start of the backswing to help get things going.
Great advice here from Jack Nicklaus about the wrist conditions and how they affect the release. There is a video to come on this also that I recently made and it really mimics the Golden Bear's advice here.

Loading into the right leg on the backswing but still creating turn of the shoulders is extremely useful to help synch up the downswing and the path into impact.
Learn how the right arm works during the backswing and how there are options of differing backswings to torque that right arm into a nice delivery spot as you head into impact
