I'm not sure why people are saying Michelle looks "uncomfortable" unless they have never stretched in their life. I don't anybody that's under 70 that can't achieve a 90 degree hamstring stretch - it's not even close to touching your toes.
I suspect it's not painful at all but fairly comfortable (unless people just mean "painful to watch", then who cares?)
Jack's putting and Wie's are the same and different:
Both looked like they have their eyes just about straight over (but not past) the ball. That's the same.
Both are close to the ball. That's the same.
I can't speak to the take away and follow through.
Wie has straight legs (likely her base is a lot more stable than Jack with his flexed knees.).
Wie's spine is straighter (likely her rotation is a lot more predictable and square than Jack).
Wie's spine is more clearly parallel to the ground than Jack (likely much better control and repeatibility)
seems like Wie took a page from Jack and came up with a better version, IMHO - everything about it is a better base and cleaner lines
sacrilege, I know
Cleaner line is not what I would call it but "I like that homes I like that"(training day reference).
