Fed's 05 and 08 RGs were pretty weak I agree.
Nadal's USO draw besides the final was pretty meek though wouldn't you agree? Clowns like LaLo, Fiasco and a washed up Youzhny before Djokovic?
And that is the reason enough to not call the draw weak.
Djoker was a former USO runner up and AO champion and world #3, plus someone who can trouble Nadal on hard courts a lot.
Who did Noserer beat for his RG title? First time ever slam finalist? Lol. His draw was weak precisely because he beat pigeons and chokers on his way to the title. He never faced anyone who could trouble him.
