Rush;
Sometimes there are teams like that in your district. I know our local high school has to play several private schools, one of which has a total school attendance of 50. If their district is like ours, you have to play every team twice.
You are not required to let every team score, but it is usually good sportsmanship to NOT score 100 points on a team that hasn’t scored on you.
The good team should have just played keep away, with a brick to the rim every 20 seconds or so, after they were leading 59-0 at halftime?
Apparently there is a rule for mercy termination of the game when scores get so imbalanced. The refs should have called the game at the half.
