"Another thing I’d say is that, while Andy really thrives against the likes of Nadal, Djokovic, Federer etc. basically on any surface, his real danger will always lie in earlier rounds of any GS and RG won’t be any different and that is, whether there’s any pressure or not. "
Err...certainly not in Grand Slams. Andy's record against the big 3 in Slams is truly woeful. Unless I'm mistaken the only one he has beaten is Nadal. He's beaten him twice but Nadal retired injured in the Aussie Open semi-finals. Andy is almost certain to lose to Fed, Nadal or the Rubber Man in Slams. He's almost certain to win against anyone else though. He's unlikley to lose early in a Slam because its best of 5 and that just makes a shock far more unlikely.
I don't think at all that it's truly awful given his circumstances. Mind you, he’s the last one to actually turn pro among the top four. He also has the kind of pressure that no one has. These things matter in a major way when you face an experienced player like Federer in the final who also happens to be an all time great.
He has beaten Nadal twice. You can say Nadal was injured (never really bought it) but Andy was already 2 sets to love up when he got supposedly injured – not that they were going toe to toe. But most importantly, he beat Nadal when Nadal was in top form. He was THE guy to beat around that time. Neither Federer nor Djokovic could do this. So let’s give credit where credit is due. Mind you also, that had he met with Federer in a qtr final or at least in the semi, you can’t say, he wasn’t going to beat Federer just like he beat Nadal. Unfortunately he’s met with Federer both in finals. I am sure even Federer knows he got lucky both times.
As to Novak, well, they’ve only met twice and while his AO final was as given as his other two finals due to same reasons stated above, he did put up a great fight against Novak in the semi. Again the match being semi made all the difference as you can see which speaks volume about the pressure.
I am quite sure, if Andy didn’t have the pressure and if he were from a country where the whole nation didn’t depend on him to free them from this 75+ year burden they have, Andy would be a multiple Slam winner by now but hey.
