Sometimes it is just politics and kids of rich influential parents not playing but coaches also need to adapt. We are not in the 60s anymore and it not anymore just winning that counts. Many HS players are minors and a coach shouldn't verbally abuse or scream at them.
Winning is still important and sometimes you can't sugar coat everything and need to get a little louder but it isn't anymore that winning justifies about everything.
Social skills do get more important and being stubborn and saying " My dad got screamed at, I got screamed at and now I scream at you" isn't going to cut it, the my way or highway mentality isn't really the state of the art,you need to communicate carefully.
