this is a great topic for discussion. I, personally would narrow it down to Tiger, Jack, and Hogan. Every player on the list (as well as write ins) are all pretty close to each other talent wise. So there has to be something else that seperates them. I chose Tiger, Jack, and Hogan because of what they had in their heads and hearts. Not to say that the others don't but Hogan came back to win after a near fatal car crash, and Jack and Tiger, are well Jack and Tiger.
What would the format be for this battle royal? One tournament? Anyone could win, if it was a series of say 12 events filled with them playing on courses that some know, all know, and none know. That, would be excitement.
