Had Fed beaten Rafa, he would've beaten Djoker in the final.
More importantly, though, he would've lined himself up for the #2 ranking before the French Open.... thus potentially putting Fed on one side of the draw and then Djoker/Rafa on the other side (if the draw riggers wisely played along)
Such a draw could've allowed Roger to win the French against Djoker. Then he would've had the Aussie and the French going into Wimbledon.
Instead we'll get Djoker in the FO final slapping around Nadal again... after Nadal has disposed of Roger 6-0, 6-0, 6-0 in the semis.... crying optional.
So that loss to Nadal was not only huge in the sense of Rafa ownage of Fed in slams and all over the place, but it set the course for the entire year .... and opened it up for Djoker.
The only man on the planet that can beat the Djoker is Roger ... but Roger will never face Djoker if he has to face Rafa each time... and Rafa uses Federer's behind as a sausage garage.
Only Fed can save tennis against Djokovic.... but with Rafa in the way.... no chance.
