Ain't a day that goes by that I wish somebody taught me D-Plane when I first started, or when I was a freshman in high school or when I was a senior in high school or when I was a senior in college, etc.
I'll repeat that.
NOT ONE DAY goes by that I wish somebody had taught me D-Plane earlier.
It explains away a lot of things. And it explains why so many greats swung the club so differently.
To me, D-Plane is THE fundamental of golf. And while guys like Nicklaus and Couples wouldn't know the difference between D-Plane and D.D. Lewis, most of us are not Jack or Couples. And I don't think if Jack or Couples were taught D-Plane at an early age that they would not have been great. It may not have benefited them much, but for the rest of us I think it's a great benefit to understand.
