S71. I am a CCS backer. Both my kids went to Los Gatos. Have a granddaughter running XC at Aptos. Love the CCS, just like you do. But it is small, very small compared to the other divisions of CIF.
I could give you numerous examples, but one: My granddaughters XC team won CCS D3 as the number one seed, over the likes of St. Iggy. Went to state with high hopes and came home disappointed with a 13th place finish. Stories like this go on and on. Yes, there are some good, very good, individual athletes, and occasionally some good teams that can compete at the state level. But for the most part CCS is small compared to the likes of the southern divisions. Orange County itself has 3.8 M people, and they don't do all that well in CIF.
Does that mean that a banner team (take DLS) can't beat the best of SoCal? No, but how many more teams can.
Take girls soccer. You have some good clubs in NorCal----Mustang in Danville, San Juan Spirit in the Valley, Santa Rosa Freeze in north county, Pleasanton Rage in Pleasanton. The others, for the most part are a step down. The first three I mentioned can compete with Slammers, SoCalBlues, and West Coast---three OC teams within a 10 mile radius. There is also Real So Cal, Arsenal, LAFC, Beach, San Diego Surf, Eagles, Carlsbad Elite------get my picture. Nor Cal has one or two teams that can compete with multiple teams down here.
Parents mortgage their lives for their children to advance in club soccer, lacrosse, volleyball, etc.
Not meant as a put down, and by the way my heart is in NorCal (born and bred there, lived there for 60+ years), but reality is scale, and everything is bigger, more agro in SoCal.
