Trigolt,

I'm sure that home run hitters have 90 degrees of shoulder rotation prior to impact - check out Barry Bonds:

It's just a different 90 degrees.

Lag is technique and the answer to "how do I get seemingly effortless - relative to hackers - power." It is not what powers the golf swing. It is what makes a swing powerful.

What I meant was, he doesn't turn his shoulder 90 degrees to his "target line". In frame 3, he has as much shoulder turn as he ever gets...and it aint much! This is an awesome link by the way! I love the Tony Gwynn commentary. As a former baseball player I love stuff like this!
