[GeronL]

He should teach them NOT to work hard and not to strive to be the best. He should just send them to public school I guess and tell them they need to get on welfare too.

I guess then he would be teacher of the year.

[First against the wall]

Actually, his job is to teach them sportsmanship and help them to better their skills. He should have, once the immense disparity was evident:

Had them practice their passing game; had them practicing plays that they were less good at; brought in some of the players who do not see much time in the game.

Instead of that he behaved in an unprofessional and unsportsmanlike fashion that makes his school look bad. Good thing he was kicked to the curb.

[Natural Law]

The Covenant School motto is:

Non nobis, domine, sed nomini tuo da gloriam. -Psalm 115:1

Not to us, O Lord, not to us, but to Your name give glory!

That's why the coach was fired!

[Thumper1960]

I would say that once the score became insurmountable, the winning team could have practiced ball handling skills, dribbled around the court, took low percentage shots. There comes a point where winning becomes humiliation. Scoring 100 points to 0 against a winless and small school borders on humiliation and senseless degradation.

Is there a place in sportsmanship for taunting?

Winning is what we all strive for. To do so without honor is unacceptable.

[Polybius]

He should teach them NOT to work hard and not to strive to be the best.

Having his athletes be the "best" would have included teaching them the meaning of and the practice of sportsmanship.

sports·man·ship : conduct (as fairness, respect for one's opponent, and graciousness in winning or losing) becoming to one participating in a sport

Having a full-court press and going for three-point shots in the fourth quarter when they already had their victory more than assured in order to publicly humiliate their opponent showed extremely low class.

Their conduct did not make them the "Best Athletes". It just made them the "Most Athletic Trash".
