Yeah Murray has something they don't have, I'm sure all kinds of players have something Big 3 don't. But they have all kinds of things Murray does not, not one thing. So big deal.All from the big 3 give their absolute best at the Olympics. All from the big 3 are devastated when they lose. The reason why they don't have Murray's Olympic success is because they couldn't handle the intensity, which is higher than on slams. Which means that Murray maybe has something which the big 3 do not. But Nadal and Djokovic still have 2 more Olymics to play, so we'll see.
Nothing to do with intensity, Murray result, but as follows:
Olympics is not the same feild as a slam, there are usually some missing.
And BO5 only in final, as i recall.
Not as competitive as a slam at all.
Also, once every four years creates a certain randomness to the result, in a way that once every year (slam) does not.
There's been enough discussion on this forum about what separates Murray from Big 3, it's so obvious, not even worth stating again.
