Hm. I consider myself pretty objective about him, I consider him the 4th best player who can pose a threat and maybe more to the top guys, meaning he has a pretty good chance at any tournament, but not the favourite. All I said was I believe he'll win a slam and dominate with Djoker next year. Not like that's the most far-fetched thing anyone's ever said, it's not like he's a low ranked player struggling to make GS 4th rounds, and with Fedal struggling this seems the most likely to me.
But if it is, saying he has no chance of ever winning a slam is equally not objective (what's the word.. subjective? Eh..), since you obviously have a deep dislike for him. I wouldn't say anyone in the top 10 has NO chance at slams, let alone Murray.
Anyway, after thinking it through, I have to say counting out Nadal would be pretty short-sighted. Triumvirate it is.
