They all got somewhat easy matchups. Nadal doesn't lose to Fish and no one ever really beats Nadal simply serving well. You need a complete game to beat Nadal. That's just not happening. Feliciano Lopez is another big serving dick, but Murray has been very good against those types of late. He destroyed Andy Roddick on the grass. Federer has had it relatively easy with Tsonga and Djokovic gets to play an 18 year old.
Anyone expect one of them to lose? Just not seeing it. I guess, based on propensity to choke, maybe Murray could lose to a big serving dick. But I just don't see it.
