Would reaching the US Open final by Nadal be classed as screwing up?The US Open will settle the argument this year. If Nadal wins, it settles the argument. If Nadal screws up, it settles the argument. It always has and always will decide the #1 player in the world. The winner has been the #1 player in the world for how many of the last 20 years???
Plus stats are there to be broken. Like Rios reaching #1 without winning a GS.
