I guess it is how you view it. I view it as Rudy is the best defender in the league and even he can't stop Joker.
It is like the Bulls in the 1990s. When they beat the Jazz in the finals, is it correct to say if the Jazz were as good as everyone says they were, why did they lose? Or is it more correct to say the Bulls with MJ were so dominant that even the Jazz, a very good team, couldn't hang? I go with the latter.
