First, Both Swings are awesome. Thank you for sharing them.

Second, The commentator shouldn't be talking about something he utterly knows nothing about.

Third, What you think you are seeing is not what they are doing.

Tiger's Hip Center is 2" ahead of his ball location and his Head is dead on the Ball at impact.
Zach's Hip center is dead on the Ball at Impact Location and his head is 2" behind the Ball.
Though Zach moved to his left side perfectly, Tiger moves slightly more.

Zach has a very small #3 Accumulator angle. Tiger's is greater. Tiger can do that because he has higher hand speed. It looks like zach is sweeping compared to Tiger. But, he's not. For you, it's just not having enough information availble to analyze the comparison. Now you do. However, you're ten times more knowlegable than that commentator.

They both have a Straight-Line Delivery Path. Tiger's is slightly more vertical. Zach has textbook form. So does Tiger. TGM Textbook (in this video anyway).

Daryl,

You make it sound like #3 works like #2. Is that right? Aren't they always talking about pulley size and hand speed? Pulley is #2, right? And those discussions are always about hitting the ball the same distance----bigger pulley requires faster handspeed to acheive same distance. How does hand speed affect ability to transfer power through #3? If I have a big #3, do I have to swing my arms slow to get it around the corner? Or can I just rotate my left arm faster? Really confusing. Let me know.
