The best coach I ever coached with told me that 95% of what you say to a player should be positive. Even when you want to provide "instruction" it's best to tell the player something they did right, address the thing they did wrong, and then end on a positive note.
You do run the risk of the negative part not being heard, as it's human nature to center on the things that are positive and dismiss the negative. So, I think you have to adapt as you go, maybe you become more insistent as you see the same thing that needs to be corrected.
Unfortunately, too many coaches think they are John Tortorella.
Hockey is a game of mistakes. If you criticize every mistake, you are just teaching the player to not take chances. That's bad hockey.
So throwing full water bottles and screaming is now bad?
Saw the same thing with that team and Coach last week. He puts on quite a show.
