2017 Top Teams in WCAL = Serra, SF, VC & Mitty & then the lower tier.
2018 - I see no significant change in the finishing order of above teams.
For many year's the Bells & SF did indeed dominate the WCAL. Had SF not lost to Serra last season the Lancer's would have had a share of the WCAL crown for the 3rd time in 3 years'. Colhenry & I both know that with the 8 WCAL schools in relative close proximity to each other the talent each school draws on is somewhat diluted compared to where DLS is situated. Here student-athletes can choose for example SF, Bells, VC, Serra or Mitty depending on family's preference. As for DLS they have the records and notoriety to pull every FB talent in their sector as THE choice as a private parochial [as in THE only choice for that area]. Combine SF, Bells, VC & Mitty all close to each other and you likely would have a WCAL super team. Year to year in following rosters DLS has larger rosters than any WCAL school in terms of sheer numbers and depth and talent. This upcoming season will be interesting though as Pitt returns loaded and DLS not so much as most years.
Plans for a new coed Catholic high school in the Livermore/Pleasanton area never panned out. Rumor had it that way too much East Bay/NorCal papal cash had to be used to settle old abuse claims and, as a result, there wasn't much dough left for a new high school. So DLS continues as the only big-time private/parochial game in town on the east side of the hills.
