The Grinder Of Pars (Semi Crocked)
Kuchar anchors his putter against inside if his left forearm and that will continue to be legal to. So it's not exactly been well thought out as far as what constitutes an anchored stroke As there are ways to continue to anchor after rules change and still be legal.
There's anchoring and there's anchoring....
Kooch's method is legal because you're still swinging the club while holding it away from your body. OK he anchors against his arm but it's still a swing.
