Other than you may have a girl that plays in the SCDSL league, your post doesn't make much sense. SCDSL "became better that CSL and SDDA" because why? Based on what metric? Profitability?
While there are some quality teams for both boys and girls in all the leagues, in general, over all (not factoring SDDA), on the boys side CSL is much stronger than SCDSL and on the girls side, SCDSL is much stronger than CSL. Glad I could clear that up for you. There is no disputing that there is more money on the girls side since Daddy is happy to spend whatever it takes to get his princess on a club team (and into college apparently) and pay for a fancy name. On the boys side, a lot of kids, baller kids don't want to pay anything. Also, why white people and fancy cars are more prevalent at SCDSL events/games. It is what it is and the mega clubs that started the league aren't dummies, they know this is all really about money over anything else for them. Not opining on whether it is good or bad.
Lastly, so it was OK for DA to come in and destroy a brand that was already serving the marketplace with a top level league but it is bad when ECNL begins "using all sorts of tactics" to protect the market and league that they created? Remember, DA could have done this long ago. they waited for someone else to take the risk and grow it into a profitable league and then decided they would try to take it over when they could have just worked with ECNL to implement some of the things they wanted to see.
