I don't have a link or anything, but I've heard John McEnroe say on more than one occasion say the Blake/Fish match was effectively the end of the J Block (and good riddance). I will say, though, that James doesn't really have any control over what's going on, nor does any player really have control over their fans. He can ask them to be quiet and more respectful, which he did, but after that it's kinda out of his hands. And as long as they allow alcohol at sporting events, the stands are going to be populated with various individuals who behave like asses.
