Well, on the surface yes, 1 player or the very small minority should not be making comments about the program. However when there is a preponderance of evidence, regular dysfunction, regular blaming of the player for issues BY the coach who isn’t coaching, complaints of lack of discipline on and off the court, then yes, players should speak their mind to get stubborn people to listen.
That was specific to this situation. I will Tell you and the BY group my son was an unfortunate recipient of an abusive college coach who had been passed along from 3 programs for similar behavior where upon the 4th program fired the coach with enough documentation that the USA Sport Governing body has sanctioned this coach from coaching again. Without a student-athlete speaking up, this abuse would have continued and frankly, all 4 Athletic administrations should have all acted sooner instead of demeaning the athlete.
When the “adult in the room doesn’t act like the adult” someone must fill that void.
