Seeking someone else's perspective is fine and often helpful, but what that article says is not just empathy. I think many coaches approach players with a statement like "Come on guys this isn't your first game, can anyone explain the 6 errors we had that inning?", no one will have an explanation and poles will be ran. I honestly think the approach below will lead to shell-shocked children as they progress in the sport, and while this approach is great for a 6 year old, it won't do the 14 year old any favors..
Excerpt:
"When you are frustrated at their performance and want to tell them, can you start with words of compassion and understanding? Step into their shoes for just a moment. Once you do this, you gain "heart" access to proceed into the reason for your high expectations and the belief that they are capable of more"
That is precisely what empathy is. Knowing where your training audience is so that you can deliver what you need to say in a way that it will be most productive.
