context is everything.
Was a response to a post including Raonic and Nishikori.
As for ppl saying none of them will win Slams - if they don't, then i don't see who will in 4 years from now for example.
A magic Jesus like player will emerge from somewhere and win them all?
From what i saw in Brisbane final today i am even more certain that in a matter of months (OK, maybe 24 of them..) one of them will be up there close.
And at one point they will start getting those tittles.
As i said - Dimitrov did it as a junior, i don't see any reasons why not as a pro, considering he is transferring greatly.
Many players have peaked as juniors and been not so great pros.
