Is it the stats? The # of consecutive matches won or # of titles won? Nah, I dont think so. Will Nadal stay in my memory forever? Perhaps not. He has just gotten a new record to his name and I am sure plenty will follow. But I'd on any day remember a Pat Rafter (just 2 US Opens) or Goran Ivanisevic (his name is tattooed in my brain) for the way they played the game, their flair, their personality. Not a Nadal... So what's your criteria for tennis immortality?
