I agree. I was an assistant high school coach and would disagree with the head coach on this. What is the point of running up the score vs the weak teams doing things that would not work against the good teams. An example is that we would press full court and win by 50 but then try to do that against the top teams and they just go right through it and beat us by 30.
Wining helps set a culture... It doesn't matter who you beat the team needs to learn how to win. It hasn't even been a year and we are "disagreeing with the head coach." I want to be clear, I do not think that it's wrong to have an opinion. The logic behind all of these disagreements isn't sound at all.
