We need to be more realistic/optimistic. In Slams, Andy finds playing Nole, Rafa and Fed difficult. I think it's a 5 set issue. His beautiful game is always on a knife edge and he finds it hard to maintain it, and his concentration, over 5 sets.
In best of 3, it's a different matter and, providing he's not injured/tired/wobbly headed, he can beat anyone, as he's frequently shown.
I agree with you entirely on this, BBH.
