I believe Tiger may already be the greatest player of all time; it's close, whether or not he gets 18.
I think, however, that he nowhere approaches Jack in terms of overall legacy. Sure, there's 30 years to go but I don't see Tiger 3 decades from now with the same influence Jack has today. From his design work to charities to The Memorial, Jack has put a huge footprint on the game.
Could there be a time when people get excited about playing a TW-designed course as they (I) do with Jack's many treasures? Perhaps but I don't see it.
Could one day the World Challenge have the same prestige as The Memorial? I suppose so but doubt it.
So, I may give Tigs an edge on the field of play but Jack far surpasses him from a world of golf standpoint.
Maybe no one in all of sport has ever transferred such greatness on the field to such success and recognition off it. So when I see GOAT references I'm inclined to give it to Jack. Add a "P" after the G and Tiger is right there.
Dumb argument? Too early to call? Perhaps but that's how I see it.
First of all, Tiger's legacy has already dwarfed Jack by dominating a sport as a black man that is primarily white. Argument already over.
Tiger also changed golf in terms of athleticism, literally changed the way the game is played. Dustin Johnson, Gary Woodland; those guys aren't playing golf without Tiger coming first.
The course designing thing means literally nothing. Hogan didn't design any courses of note, Vardon didn't design any courses of note. It's arbitrary. Plus, Jack is in his 70's; he's had much more time to design courses.
And to say that Jack surpasses him worldwide is ludicrous. Everyone knows Tigers name, even if they don't follow golf.
Jack has a large footprint on the game, but it's nowhere near the size of Tigers.
