As I have said, certainly some league punishment is in order. I'm not trying to minimize the incident, but what exactly are we as society trying to do? I would assume sending a message that physical fighting between couples of any sort is a no-no.
But, if one was an NBA male and one a WNBA female, and the NBA male ends up doing more damage on the female than vice versa - punish them equally? Or take the societal view that its always the man's fault for striking the woman and only punish the male? Or what, exactly?
I just think you can punish those involved and show an incident as unacceptable to the rest of the world without raising it to the level of, for want of a better term, a federal case. If no police had been called, by family no less, we wouldn't even know about it.
