she is good. Lebron and Pippen having a tantrum and leaving during the fourth quarter isn't the same because that game was lost and he came back for the next game. Further, both your Lebron and Pippen examples have been discussed on this board. This sort of thing is rare and when it happens, it gets talked about on CB.
Maybe unprecedented is the wrong word, but I think we can agree its newsworthy. And to me "newsworthy" = "CBworthy".
