Coaches are always asking about discipline and remedies for when their youth players aren't
listening. The question is usually asked with the mindset that the players are to blame.
Before I answer, I take a deep breath, assess how much I value that coach's friendship, predict possible reactions, then deliver my answer in my usual pleasant and positive disposition: 95% of the time it's YOU. Maybe 96%.
OK, let me rephrase that in a more productive tone and manner.
I offer this one bit of advice that I find helpful: blame the players LAST. This forces you to examine as many possibilities as possible and forces you to reflect on your session. (This is a good time for an "It's not you, it's me" reference)
