I kinda had a moment like this a few weeks ago. I'm an Assistant Coach for a Youth team and we were getting handled by another team. I had been preaching to the Head Coach that our practices weren't really doing a lot for the players the week before, but he did little to change our practice plans. During the game, we got something like five Illegal Procedure calls on us due to being disorganized. I was more embarrassed by this than the score and I tell the Header "we can do a better job of preparing these guys than this." 

 

The Head Coach whirls on me with something close to true anger and says "we've practiced this stuff for weeks! What else are we supposed to do?!" I tell him "I understand what we were trying to teach them, but they ain't doing it. It's up to us to get them better." He stormed off and left the conversation. He never did adjust our approach and we just got smoked in the Playoffs.

 

A lot of times, people don't like criticism when it begs for action on their part that doesn't include talking.
