There's no 'easy'. It's just a draw. A draw that's equally fair to all players. If it conspires that Murray has some lower-ranked opponents than expected, that's down to higher-ranked players being beaten. It's Murray's job to beat whoever is in front of him and whoever it is will have earnt their place.
And the court you play on has nothing to do with the draw. The top men will always play on the show courts, because they are the main attraction. Murray being British helps, but he's also the fourth best player in the world. Roddick would be on the show courts in America. Berdych would be on the show courts every mach if there was a Czech Grand Slam.
And he was on Court 1 on wednesday.
Oh yeah, he gets the pick of the courts usually, unlike those poor Wiliams'.
In tennis I think the best guy usually wins so regardless of how the draw starts, by the 3rd or 4th round you're either playing guys who are of a reasonable quality or just in the form of their lives, either one is dangerous imo.
