You almost feel sorry for the hapless Scotsman putting in the effort to progress since you know that even if he were to reach a stage where he would meet a top 3 player - they outclass him by such a margin that, whether it be a semi-final or a final - he always gets completely embarrassed. There is no shot he has that can even remotely challenge Federer, Nadal or Djokovic, and whilst each of their games are completely water-tight, Murray has glaring technical errors (2nd serve, forehand, volleys, overhead). Murray is a sort of whipping boy to the big 3 - him being in the top 4 (and somehow managing to make the semi's on occasion) always guarantees one of the big 3 to have a very easy passage to the final without being tested at all. The less-tired guy will have a distinct advantage over the whoever had to play Federer. I wish there was an actual big 4 where the 4th member genuinely had a chance of beating his top 3 opponent in the semi-final. It would make the finals of grandslams much more equal and exciting.
