According to MTF tennis experts:
1. Wimbledon later stage = clay.
2. RG = clay.
3. Murray >>>>> Djokovic as showed today.
4. Djokovic 2013 = Nadal 2013 (clay).
5. Murray hasn't peaked yet/Djovic&Nadal way past it.
Obviously it's not difficult to see why Murray is the clear favourite for RG2014. Any flaws in my theory?
Then Federer and Sampras would be the true clay goats
I guess Wimbledon is clay only when Nadal managed to won it, mate
