There are two things I'm not sure I love about it and that is that I'm not sure one has a right to go through life never being called anything bad, especially when doing a terrible job.
The other thing is that I am under the impression AC Green used to routinely get made fun of in game for being a devout Christian and I'm sure Tebow is too, and nobody really cares about that, reinforcing the notion that the league is essentially a pick and choose arbitrary league when it comes to enforcing morality.
However Rondo certainly has no right to go through life like this consequence free either, and it being their league the NBA can do what it sees fit, and protect the image of their league as they see fit. Personally I don't think this holds a candle to what Sully was accused of, but that's just me.
