IME lower level coaches underestimate what the kids are capable of learning and tend to dumb things down more than they have to. Push them and let them rise to the occasion. They'll have more fun that way too. JMO.
I 100% agree with this, watch 10U and 12U and mimic drills. I would say latch on to some folks and take in as much as possible. I was lucky to coach travel BB first and learn from tons of great folks. By the time DD's were born and played I had a partial clue. Also ask questions at lessons and observe don't just sit in the lobby. Number #1 is progress is made between practices so have fun and play catch in the yard. It flys by too quickly.
