nadal is right back in business if he wins Barcelona and Rome masters. that will get him going again.
I think he'll win those if Nole doesn't come back until RG. And Nadal is very rarely tired on clay no matter how long the season is. And very rarely injured too, in fact, never. Nole probably wants to stay fresh and wants to avoid playing Nadal until RG, if that happens. A lot can happen in between too. Stan has just opened the door too so who knows.
