Awesome post.
But. If I may interject a little bit of a tactic I use to motivate my team to get fuckin goin (only in competitive) after a silly goal.
I'm on Xbox, so I don't type much. I'm not a jerk who spams what a save after someone misses. Or nice shot on a misshit. It happens to everyone, I've hit more cross bars and posts in the past few days than I have in my life.
But. When one of both of my teammates are playing weak and i believe that they should play better and we're down a goal or two in the first minute I'll hit the forfeit button.
Now. If they forfeit, so be it. I know that deep down they're quitters. They wouldn't come back for the W even if they want to.
But, if they're like me, if someone else hits the Forfeit button in the first minute, it wakes me up and serves a dose a motivation. Of the 10-12 times I've done this in my measly 200 hours of mostly competitive play, I'd say 8 of ten didn't forfeit and 7 of those 8 we came back and won. Several times, when we've tied it, the other teammate/s have hit the forfeit button sarcastically.
In my book, these people are winners. I'm not a quitter but sometimes people need to be reminded to wake up and play some fuckin ball already. A quick forfeit can be just the smelling salts these people need to get angry and play.
Lately I've been using some more text like "let's go" after a goal to draw even or "30 seconds come on man!" If we're down a goal with little time remaining.
I wish we could do custom preset message on Xbox.
