Indeed. If Murray can get to #2 and Federer is drawn in Murray's half, then conceivably Federer can beat Murray in the SF (or Murray loses to a mug before the SF) while Djokovic takes out Nadal in an epic 9 hour semifinal leaving Djokovic toast before the finals.
Obviously this is not going to happen, but it's a nice thought.
I think there are more chance for Murray to be number 2 before RG than Federer because we are coming in the slow hardcourt tournaments in Indian Wells and Miami which Murray loves, he's in good form, Nadal we don't know yet, and then Murray played well on clay last year.
And yes it could be a very good case for Federer for Roland-Garros
... even if he doesn't draw Murray, at least he would be sure not to draw Nadal in SF
And even in the long term after RG, it would still be great for Fed to be sure to avoid Nadal before the final if Djokovic and Murray are numbers 1 and 2
COME ON ANDY !!!
