It would be interesting to see how many kids could go through a pace like that for multiple seasons and stay in youth hockey? My guess you would lose more than keep in the sport.
Burnout is one thing but what I've found interesting in the kids I've watched play and as they get older is how many fail to improve as they age. Some I've seen stall-out as freshmen making varsity and by the time they're 18 they aren't any better than they were when they were 14. Some you see from 16 to 17 and not one lick of improvement and some actually decline.
So just because the kid plays 75 games a year as an 8 year old it is no assurance the kid will a)be any good as a teenager and b) will want to stay with the game.
At the recent WW Junior Championships Bracco was one of the standouts for USA. His brother is now playing for the 07 Gulls. The parents on that club are not new to hockey.
Who are the 07 Gulls?
Team from Long Island where the parents drive z28 irocs , eat lunch at strip malls, and use lots of hairspray.
