But you are getting away from the initial debate. Why is what this guy did an example of bad coaching? If there was no obvious threat to the players on either team, how is how he handled it a problem?
You seem very irked at the situation, and I'm asking how you would do it differently. If any combination of players is scoring points against the other team, how (and why) would you go about 'slowing things down' without it being obviously insulting to the other team? You can't just yell 'slow down, these guys suck' on the court.
In the end, how do you let the other team

without it being totally obvious? Plus, how do you even keep the game fun at that point? The worse team is still going to lose, and the winning team has to now go through the motions to burn off the clock. That seems pretty pointless to me.
