Seems like some would like to take the "time" part out of the equation, when talking about the greatest of all time.
Right now, McBeast is the greatest. I wouldn't argue against that. There's every expectation that he should win or be in the running of any tournament he enters. Right now.
Time is the difference maker. The Champ played at that level for over a decade, winning nearly every tourney he entered. You could argue that the game's changed and technology has advanced and it has, but all the competitors were playing with the same discs then and everybody was getting better all the time and Climo still dominated. Even as things changed, he stayed at the top, and even now he's likely a favorite in any Master's division tourney he plays 25 years or so after his first title. What was it, 9 straight world titles, 13 in 20 years, give or take. That's GOAT level play, no argument to be made.
To dethrone Climo, McBeth would have to keep playing at the level he is now for about another 10 years. Actually, I guess he'll have to get even better, as Climo did, and keep advancing his game to stay at the top for a decade straight. Then you can start having the conversation, but until then you'd be ignoring the biggest part of the GOAT..... time.
