Re: 33 combined slams vs 1 - does Murray have the right to be in a "big four"?
Look at Djokovic before 2011 and after. I expect the same for Murray though not as well as Djokovic.
It's a matter of time before Murray collects more slams.
Murray is unlucky though for years he faced Fed,Nadal and then comes along Djokovic dominating and still is.
Nadal is injured, gone. Fed is nearing the end but now he's facing Djokovic in his prime. Otherwise he'd have A LOT more slams. Tough.
