All they need is to become a bit less competitive. That's what eating these guys. I remember Nole taking injury timeout just when Andy was supposed to serve for the match in the 5th set at the 2012 USO. Nole got booed by the crowd and as much as I like Nole, he too is suffering from the same disease. He did that to Andy at Cincy too in 2011 when he was on that superb run. In the final, Andy took the first set very quickly and looked very strong at the start of the 2nd set. Next thing you know Nole calls in the trainer and then pulls out of the final match citing injury not willing to give Andy a fair win and the mental edge just before the USO. He then went on to win the Open. It's a put off for me especially if they do it in big matches. I really hope Andy learns from all these and never ever does it to another human being. I want to like everyone but sometimes they make it very hard.
I say don't get too hung up on these records. Records are meant to be broken. That's why they call it a 'record'. It means this is a target and open for everyone to break it. And given the advancement of the technology these days, it's more than likely that things will be more and more in favour for the players - be it the constant change of the surface or new racquet technology etc. and who knows what else. But they will be all designed to help the players so that they can win more, break all sorts of records and draw more crowd, money and rating etc. So there's really no point becoming so obsessed with records since all of them will be broken anyway. Look at Sampras - he does say it doesn't bother him as he's accepted it and even for it. The fact that he was the best player in his time makes him more than enough happy. So if nothing, the current players can at least learn from the past champions and see for themselves how it is truly like in the long run.
