Logic behind "no dunking in warmups"

[ChrisSportsFan]

I remember when sometimes we would get about 5 minutes before the refs came out. We like ta tore those goals out of the ceiling. It's amazing how much higher you can jump with a pep-band, cheerleaders and a packed gym. Seems like it took the rest of the warmups and a couple of minutes of the game to settle down after that. Until we settled dowm it was almost useless to shoot. As a player, we loved to get in the dinks, but I can see where a coach wouldn't like it and if a goal did bust, now the game is either going to have to play on another night or it will be really delayed.
