Success is never final, but failure can be.
~ Bill Parcells
If I have affected someone in a positive way, that means a lot to me.
Something goes wrong, I yell at them -'Fix it'- whether it's their fault or not. You can only really yell at the players you trust.
So if the players trust the coach, it's not a problem. If the players don't trust the coach, it is a problem, and vice versa.
