This thread is fine, and it belongs here in the NBA Live 2005 section as far as I'm concerned.
I guess it wouldn't be a completely terrible idea, it would add the element of bloopers to the game. It might get annoying though especially for people who are new to the series and aren't used to the controls. I would assume that the shoot button will have a different function when playing defense so we won't accidentally attempt a tip at our own basket.
