The coach had to respond. His team was being trashed by their own school. He did the right thing and tried to set the record straight. Should his players go thru life thinking they participated in a shameful victory?
Yes.
When I was in high school, I played on an intramural flag football team. One of the other teams was made up of cheerleaders.
We beat them 98-0 and were striving to get to 100 points. A bunch of geeks with no chance of ever dating cheerleaders, we instead took it out on them in the only way we could.
Is that mature? No.
But we were 15 and 16. This coach should know better that running up the score to try to hit 100 is classless.
