The Coach would benefit by closely reading that note. The student is articulate enough to make several points regarding actions and habits he considers wrong or unproductive. If he is wrong, this should be explained to him why he’s wrong. This is not the Army, its high school. If the Coach could put his fragile ego in a box for five minutes, he may learn how to change a losing team into a winning one. I guess the students get no first warning when it comes to the all important football team. Kicked off the team for the season is way over the top. Nobody got shot, or even used profanity.
What is the saying? The more flak, the closer to the target?
It’s too late, the coach has lost the team by playing daddyball. He should be fired because he is a loser. The players know who is good and who stinks. When the coach seems to not know, then he loses the team.
