From what I see, the biggest disparity has been among NorCal and SoCal parochial schools. It’s chiefly because Bosco and MD opened their doors to Black and Polynesian players and the regional talent has flooded the school ever since. It also doesn’t help that they run the spread, which gives several players the opportunity to showcase their talents.
It appears that Bosco and MD just mastered the Blueprint that was laid out by Bishop Gorman. And it’s worked out great, especially since LA is a football hotbed.
I’m glad that Riordan has opened up their doors, as well. It remains to be seen the level of success that they have. As the kids still have to produce, which takes quality coaching and training.
I’ve said it on other posts, but parochial schools in cities like Sacramento, Fresno, Stockton, and East Bay could all produce teams that could compete with Bosco and MD.
But to do so means that you change your identity as a school…. I’d say that this model has worked out well for Bosco and MD.
