I thought that too, but only 1 major win and only 16 PGA tour wins to his name (which seems crazy). Although his annual success at the Masters, regardless of his advanced age, will help. He's obviously a massive fan favourite and a great fit though.
Nick Faldo is a 3 time Masters winner and has 6 major wins. He's 65. I'd have to think he's a good candidate? (yes I had to just research it a bit to find his name). After that, I think it's Phil and Tiger, which makes me sad (and feel REALLY old).
