There is a fairly long list of better irons players than Tiger, but most of those don't have a short game like his. Tiger's iron game, especially his long iron game, is the best in history. If the PGA Tour had strokes gained approach before 2006, he'd be first pretty much every year of his career.
Ok, but last year he was behind Stenson, JT, Grillo, Scott, Hideki, Kokrak, Furyk, Casey, Conners and Cantlay. Right there with Brooks and Rory. Stenson's SG approach are particularly bonkers, and have been for a good while...for many of the seasons Tiger was ouched.
