Will we ever have another Top 3 like this in men's tennis?

This list is quite impressive but if history is an indicator, which it typically is, I would venture to say we will. Nobody thought anyone would ever be as good as Borg, Lendl, Conners, then Sampras, Becker, Agi... somewhere, there is a kid on an empty tennis court hitting a basket full of tennis ... In the meantime, I am enjoying the heck out of these guys right now!
