JK - I know I'm assuming that architecture plays a role in identifying the greats, since any 'playoff' amongst them would, for me, include only the professional grand slam winners; they'd have to have proven their ability to win the big ones on every style of course and in all conditions. Next, for the test you had in mind, I couldn't go with either The Old or with Augusta, or with any course where either Jack or Tiger won a major. I think I'd pick Paul C's course in Cabo.
