Sorry MAP, but you do the memory of Mr. Sparks a disservice with an error of ommission, and give the ECNL too much credit. The most problematic, non-negotiable demand that the ECNL clubs made on CSL was that their ECNL teams would always be Premier -- no relegation. Yes, some of the other demands they made where not so unreasonable, a middle ground could have been found, and Mr. Sparks made many mistakes. But telling CSL, a league who at its foundation believed in promotion and relegation, that 8 ECNL teams every year would be Premier, regardless of their performance, would fundamentally change CSL. Not just the control, but create different classes among its member clubs, and who knows what the fallout might have been from that.
As for those ECNL games against the non-ECNL SCDSL teams, the ones that lasted I think two seasons, the ECNL clubs viewed them as a joke. My DD's non-ECNL team beat Slammers ECNL, the team that had Kayla Mills on it and was probably the best in Socal at the time, in one of those games. However, neither Kayla nor another 5-6 starters where anywhere to be found for those games. They brought up B team players. The exact quote from the Slammers' parents at the time "you did not play Slammers."
Some of us lived through that turf war. Most of the ECNL clubs (Surf, Slammers, etc.) wanted a change in control of CSL Pemier even before ECNL existed. I do not blame ECNL as a league for the break, I think the responsibility is shared by the ECNL Socal clubs and CSL.
