Unfortunately for those of us with 9/1 compliant teams, I think the trend of starting boys later in kindergarten had already become prevalent in larger metro areas 13 or so years ago.

I think a "good" team from a larger city (all over the U.S.) often 5-8 kids older than 9/1. It may not seem like a big age difference, but on the field sometimes it's hard to believe a team is in the right grade (and that's without event talking about repeating 8th grade for lax, which I don't think is that common outside hotbed private schools yet)
