I think anyone taunting to this extent is over the line. Trash-talking is one thing, but this went way beyond that, and you can bet that if it had been one of the C's, there would have been a technical assessed. That was really my point here, trying to highlight the fact that the refs were grossly negligent in this game, and heavily biased in the Hawks' direction ... regardless of what the intent of Horford's actions were, they were a classless move.
