They used to say McEnroe's antics were bad for tennis. Why not say the same about Serena in this instance?
Yes, they did. Connors, too. But also, not the point.
She was getting her butt kicked the whole match. Couldn't get first serve in, was broken, couldn't put the kid away in any circumstance during the match.
She redirected her frustration towards the umpire. All he did was enforce the rules, and then put up with her hysterical antics, until she forced him to put the rules into play again.
Then she made the awards ceremony all about her (" we'll get through this"), while along the way dragging her daughter into it (WTF?), gender bias, and other distractions---anything to deny the fact that she looked like an aging tennis player forced to give way to the next gen's talent.
