What a lot of nonsense, there are always good players around: Connors, Bjorg and McEnroe; Becker, Lendl and Edberg; Agassi and Sampras.
Murray isn't better than any of them so the era he's in matters not a fuck.
There's no shame in that.
But it's a bit of a shame people making excuses for him. The only excuse is that he hasn't got the required part where it matters at that level - in the head. Colin Montgomerie was the same when it came to golf and majors... great talent, but just couldn't deal with the pressure.
It'd be a start if he got rid of his mummy from his entourage...
