Rafa will continue to beat non-top 10 lesser players on clay and win tournaments if Djokovic and Murray continue their poor form for much longer.
Even if they get back their form, it might be too late once Rafa builds his confidence and head of steam.
I'm not entirely happy with the Swiss Assassin's absence from any clay events, but maybe it is a strategic move on his part to come into Roland Garros very fresh while the others have played a lot. Rolling out of bed and winning the AO is one thing for the ultra-talented Federer, but clay is the battlefield of the gods. His strategy could backfire with an early exit at RG from lack of play on clay.
If Rafa can stay healthy and wins RG, he is more than capable of carrying that play to Wimbledon, even though he has not done so the last 5 years.
Respectfully,
