you can't be serious.
Mirnyi has won many GS also with other players. And he was the best player on court at the FO final this year.
When you see Zimonjic's record, he played well esp. when he played with Daniel Nestor. He hasn't won any GS after their break-up. Similarly, Mirnyi won with Björkman in 2007 and a gap of 4 years to win a GS. That makes me thing he won just because he paired with a player like Nestor. Anyway, Mirnyi is not that bad player.
