The argument against court storming is exactly what you put in your last sentence. You lose a game and are very emotional, and rightfully so, and some drunk college kid runs up to you and gets in your face and screams F' You! Are you okay with the emotional response that might follow from the player?
It is just a matter of time before there is a really ugly incident and that will probably spell the end of letting fans on the playing surfaces, so enjoy them while you can.
That kind of thing can be monitored by security personnel. The "court storming" doesn't have to be a drunken mob. It can be reasonably safe and orderly. I thought the issue with Haarms last night could have been avoided if he moved his sorry butt a little more quickly, but also if our security was positioned to slow down the crowd getting to the court. It was a minimal issue to begin with.
