This goes for everyone, regardless of gender....
Particularly recently, a disturbing trend in youth hockey in the States has been to jump way too quickly from coaching the technical fundamentals to ATTEMPTING to coach "system play". I've seen/heard way too many 8U - 10U coaches brag about how they've taught their teams to 'trap' or 'weak-side-lock' or whatever. Honestly, what a load of solid waste from a male bovine.
At those levels, we should be focused on teaching our teams to skate, pass, handle pucks, shoot, and compete. Sure, they also need to learn simple team concepts such as defensive zone coverage and breakouts; but wasting precious ice time teaching a complex, overarching 'system' to younger players only stunts their skill development and creativity.
I had a long, drawn out argument with a 10UBB parent at the start of this season - he was adamant that I should be teaching 'system play' to the team. I demurred and tried to deflect the conversation to a different tack. Of course, he was groin-grabbingly persistent - even in the face of my obvious reluctance to 'go there', so I finally flat out refused and said the following:
"Shawn, I would waste the entire season trying to teach this group of 9 year olds how to trap and then transition to an aggressive 2-2-1 forecheck...and most of them STILL wouldn't 'get it'. Instead, we're going to work on skating, passing, shooting, and competing. And we're going to work on those 4 things again and again. And again. And we'll work on them next year. And all through pee-wees, too. Then, when they're 13 and 14, they'll (a) be mentally ready for 'system play', and (b) be able to execute the fundamentals well enough that we can teach a 'system' in about 45 minutes...instead of wasting an entire season."
He was unconvinced. Until last week, when he came up to me, shook my hand, and told me that his daughter had improved more this year than she had in any year before now. He didn't tell me that I was right about the systems thing...but he didn't have to.
