Nick Faldo was saying on TGC telecast of the 3rd round that Tiger's been working on less left arm rotation on the backswing. Guys, Brian said this is what Tiger should be working on. WOW.
Simple, you just have to LEARN to not rotate the club so much. It would be really simple to be honest. You just go, "Tiger here's the butt end of the club. Here's the imaginary plane line. Keep the butt end of the club pointing at this line in your backswing."
He'd pick it up in about 10 swings or less and he'd be driving it a lot better imo.
Thanks for explaining Brian. I think Haney's really book on "putting on an arc" and "releasing the putterhead". The result would be more wrist movement. What's interesting is that he's making fewer important birdie putts but leads the tour in 3-putt avoidance.
