I am sorry but if they have gone 1-11 against Rafa at RG, then they are easy. Please do not use the success that Roger and indeed Novak have at other slams to show they are greatest competition on clay. Clay is without a doubt Roger's worst surface. He is the grass and HC GOAT. Rafa's toughest competition during his peak years was a player who's worst surface is clay! You can't have it both ways here. You claim the dominance Rafa has over Roger and Novak, the 11-1 you boast. Then you say they are greatest opposition. I am sorry, you are not greatest competition if you both lose 11 straight matches combined against him!
What it doesn't say much about is that Rafa needed Roger, who was dominating everywhere else to step up on the worst surface also, because Rafa had no one to compete with.
Roger haters like you claim he had it easy against Andy, Lleyton and others of his generation. They would all be multi time champions without him. You are using Roger's success on non clay surfaces to make it seem he is a worthy foe for a Clay GOAT. Sorry, seems like contradiction to me. Amazing how many Roger haters are completely blind to their own contradiction at times.
I guess the same applies to Novak. He is much superior HC player, his best surface. I hate to say this but how many times did Rafa play Novak at RG? How many times did they play at AO?
