I get your lament. The options situation has not changed much in 10 years for the sole focused players. But to get a good number of games you have to enter tournaments. Your example of Bantam - AAA has 6 games so far, AA's have had only 13. So the point is that a 20 game HS season is an improvement and is typically augmented by a couple or more tournaments and scrimmages to bring the count to over 30 games. Many feel that this is plenty for high school where their child also participates in the many other important weekend activities or sports which do not have even half that game count.
A simple step but not a solution is to get California kids more games. I'm not sure why minor AAA teams aren't offered the SCAHA scrimmage games anymore and are forced to find their games out of state or to arrange a few scrimmages. Also letting the flights scrimmage each other as part of SCAHA. The biggest issue CAHA has is the loss of players at the upper age groups. IMO, this is due to having a competitive place to play, convenience and costs. It is also due to education.
If you have 60-90, 2002's and 2003's that have left California then there is a big drop in the talent pool at both AAA & AA.
As I understand it all roads usually go through juniors. Most kids that go to prep are going to have to go the Jr route. Even if the player stays in CA through high school and then goes to prep for the extra year instead of straight to juniors.
If the system stays the same I look for a club or two to potentially forego CAHA AAA and consider to just to do it on there own if that is possible. What do you get out of it besides a few games against teams that you can scrimmage anyway.
