When the margin is 30 you call off the press.
Given other factors, the margin could even be much less to call off the press. If, say, you’re playing a team that hasn’t scored a basket all game, I think you call off the press immediately. Coaches/teams can tell when their opponent is clearly outmatched. If, however, the only reason why you are winning is because of the press, then you can keep it on for longer.
However, given this spoecific circumstance, it should have been obvious by the time the score was 15 or so to nothing, that the losing team was not going to be able to do much, and it could have been a “subs play the whole game” type of thing, and the press comes off immediately.
If I, as a player, were ever subjected to this type of thing there would have been “accidental” elbows throw all over the place, especially when being trapped in a full court press when my team is losing 30-0. Luckily the team has a better attitude towards arrogance/humliation and/or tolerance than I do.
I don’t want to get irrate over the situation, because I have been on good teams that have been forced to play bad teams, and there are times when “bunting or swinging at every pitch, just to make outs so you can go home” (or letting a team score, or to stop trying altogether) is more insulting that just playing the game at a reduced pace. But, the full court press is a deal-breaker. If I were the school’s administrator, I would be justified, as well as, compelled to call the coach into the office for a chat, given that now the actions of the team/game are now the school’s reputation.
Anyway, lunch over … back to work.
