You know, I think that anytime one of these incidents gets publicized, the better. Im sure the OP is correct and that many, many such incidents take place and we never hear or know about it. But rather than use that as an excuse for Wood's actions, I think it we should use it to highlight how insane and megalomaniacal some of these coaches are. Many of them do not appear to be normal humans. Many are not well rounded but have lived life in a bubble, going from school boy star athlete, to college player, and then on to some post grad bball position before getting their chance, finally, as the head honcho who can then unleash the abuse they used to receive unto others.
In no other endeavor would such behavior and abuse not result in immediate firing save for the military (where you sort of sign up for this type of treatment..and it is likely necessary to keep order) .
You can call me soft or say that things are not as they used to be and I would say THANK GOD they arent as they used to be. The reason these incidents between coach and player (much like parent /child or teacher/student) are magnified now is because we have evolved (well most of us). Most humans realize that humiliating subordinates in position, age, or physical stature is not OK.
Shouting like an idiot at a kid because he didnt do what you wanted him to do only makes YOU look like the immature moron who should be the target of the invective.
