Has nothing to do with feeling noble or warm inside. Are y'all are saying that the coaches who don't milk the clock are the real jerks because they're trying to be holier than thou? Consider that it could simply be the belief that the players are learning more by playing this way than the other.
I seriously doubt the players care one way or the other as long as the coach is not being a jerk and making them feel uncomfortable. I can't imagine that a player is going to walk away with a life lesson or even a warm fuzzy because their coach ignored the clock.
One of the duties of a coach is to position their team to have a chance to win. It is up to the coach as to how this is accomplished. You can do it with class or you can be a jerk. But to lead your team in a timed contest with zero regard for time management is a disservice to your players and pretty selfish.
