a. But there's really no place to put this team. If you move them down to the bronze bracket they'll wreck the new teams coming in. If you keep them in the silver bracket, they'll have 1 team they can beat (and unless that team gets upgrades, wreck). You could make them drive long distances to a more balanced silver bracket but CSL doesn't like to do that because it leads to people lobbying to be placed into brackets they can win. If the entire point is to balance the scores, it's failing in these 2 examples.
b. It's a much more common problem in the bronze and silver levels where you have teams and players that have been at it a while. At the bronze level you get new teams like my son's AYSO team (example 3) that go in and destroy everyone 12-0 and then they aren't ready for league cup because they haven't had that experience. And you get new teams like the new AYSO team (example 4) in the bronze bracket which lose every game because they aren't playing in a new teams bracket.
c. Silver elite and gold tend to work a little better. There's less shame for a silver elite team that struggles to play down to silver (my son's current team has that dilemma). But take a relegation to bronze and the team tends to fall apart. I'd bet you a drink this team that lost every game DOES NOT get relegated, and it would make no sense in any case to promote a weaker team over them (which I bet, notwithstanding the obvious signs, will take the promotion).
d. The answer would seem that particularly in SoCal where we have a wealth of teams would be more brackets, but that would mean more driving for everyone, which is the main problem parents seem to protest.
e. The team in Discovery that gets destroyed though can adjust the following year relatively easily because again there is that choice. And they can sell it to the parents that it doesn't need to be forever. The teams in my example have no happy outcomes if the CSL rules are applied as is: the silver team will get relegated and stomp on the bronze competition, including a raw new team, the bronze team will take its promotion and get stomped on in the silver team's place (and more badly than that team), and the newly minted club team formerly AYSO will likely dissolve since the kids don't like to lose every game (many by double digits) and the parents will blame the coaches for not developing their kids (which should be playing MLS next after all).
