I don't think the question of whether or not Boeheim was out of line is relevant. Even if he was, what Blue said on Twitter was inappropriate.
I recognize that some of the posters on these sites are kids themselves and think that personal attacks are ok when it doesn't pertain to SJU, but in the adult world that is not how one communicates. Blue's tweets are particularly inappropriate given the gravity of some of his unsupported claims.
Blue touts himself as an adviser and confident of these kids. His tweets set a poor example and suggest an immaturity and lack of judgment.
Dave -- you credit Blue for speaking his mind, but there is a difference between speaking ones mind and speaking everything that comes to ones mind. The first is an admirable character trait, the second is the mark of a fool.
