Like this? Right wrist cock, soft arms, and no extensior action! He cranks it up to the max, lets the air out of his arms, unwinds hard, and walks 350 yds to hit his wedge. You can't have your right elbow bent this much at the top using extensor action.
Uh, MJ...I'm not so sure Big John Cocks his Right Wrist at the End of his Stroke. I saw an overhead view in a commercial photo a while back, and it looked to me like his Right Wrist remained Level. Like you, I had always assumed that it was Cocked! Maintaining that Level Wrist despite such a long Backstroke is why his Right Forearm (and Elbow) gets into that positively outrageous -- but geometrically correct -- 'flying' alignment at the Top.
Would somebody please find and post such an overhead? Let's check it out!
