After the game is already lost?
Good strategy.
Well. I guess you are not interessted in a conversatiom. You are more of the i get my crowbar and hit everyone who doesnt do the things i want them to do.
However i'll give you somwthing to think about anyways
First of all there is a half time where he can get in their faces if he thinks that is what the team need to win
Them there ia also a next game. That means alot.of closed sessions where he can chew people out or have private conversatiom with one player who he thinks needs to be handled that way.
A season is not lost because of one game. And if players play soft there may be more to it then those simple ideas like "they may be just sluggish" or "they are repleted because they earned their paycheck anyways".
But of course you cam always just chew people out. Maybe you dont have another way to solve problems. I prefer a HC who is able to choose what kind of solution he wants to use. Btw that is a reason you pay those people in leading positions so much money: they have a brain and are able to use it.
