I haven't been in soccer long enough to know, however I do know a few people who failed to get into the AYSO Extra team for their regions, and then went to a flight 3 club team. We have been through 7v7 and now into 9v9 and I have yet to see a flight 3 team who I think to myself "These guys would easily win AYSO Extra in South OC". I just hope people aren't paying the regular sums that get banded around to play on flight 3 club, when AYSO Extra is so much cheaper and a better environment for their kids to play the game.
p.s. here's the exception that proves the rule BTW. Last year when my son was in United their first tournament also involved an Extras team, the core of which this last season became a United team from another region. The Extras team beat them 8-0. When this Extras team became a United team, they tore up several tournaments, being only stopped by the TFA pre-academy team. These kids were superfast and could shoot high and into the corner from outside the 18. But it was some of the ugliest soccer I'd ever seen. Keeper would punt to the mid, where one of the team's core players would just try and out run everyone and shoot from a distance...very little by way of passing, very few skill moves so when they ran into a team that actually perfected the passing game and could run with them, they totally melted.
