So if I understand you & I agree that the top 3 teams or the upper tier of the WCAL league has been fairly consistent, correct? The middle tier of Mitty & Bells is a bit in question this year as Bells seem to be dramatically down - which appears more from a talent standpoint than anything else [and so happens to even good teams occasionally].
Granted the lower tier of SF teams has been weak for a number of years now and specifically hurt due to smaller roster sizes. Whether than continues or not is anyone's guess.
Yes, I agree with the one caveat. It assumes those top 3 WCAL teams will have continued success to bring their overall numbers up and that is certainly not a given. And with the silly CCS point system, a team like Serra wont be chosen to play in regional unless they win their division since their point total is not likely to be high enough to be selected as runner-up. (whether a runner up deserves it is another debate! lol)
