What do you mean earned a cakedraw? Draws barring limitations of not facing other top seeds are all random
. Maybe since Federer is god he should work his magic on a draw
As you said randomness leads to lucky or unlucky outcomes.
Of course in the long term supposedly it all evens out.
But the draws especially with nadal now in 5th and Ferrer in 4th the rankings may be the difference between winning or losing a tournament.
Look at the AO. Djokovic, apart from the Ferrer match, played average tennis. Had he drawn Murray in his half we could now have Roger or murray as the AO champions.
