John mcnroe has offered to help roger beat rafa and roger has turned it down. is federer right or wrong?

BEAT RAFA?! Federer has to first get by Djokovic or Murray to get to Rafa. I don't think he will meet Nadal again this year if Andy and Novak are in the same tournament. Roger is on a combined 0-11 losing streak against his 3 main rivals (Nadal-5, Murray-4, Djokovic-2). And if Federer somehow gets to a final to play Nadal, there is nothing that Johnny Mac can tell him (or show him) that will help Federer deal with monstrous, brutal, heavy forehands aimed at his one-handed backhand, over and over and over again.
