Sorry - I wasn't trying to disparage St. Mary's in any way. And I don't think I specifically said that Moreau's win over Piedmont was "better" than their win over St. Mary's. Using the Calpreps rankings, either one is better than Marin Catholic's best win, which is St. Ignatius. I admit that I used the Calpreps rankings to place Piedmont above St. Mary's. Those are both subject to change dramatically this weekend with Piedmont hosting Mack while St. Mary's taking on Riordan.
The schedule strength discussion is interesting. If Moreau runs the table, they'll have wins over at least 5 likely playoff-eligible teams (St. Mary's and Piedmont in Div. IV, Kennedy in Div. III, American in Div. II and Irvington in Div. I). Marin Catholic will have wins over Justin-Siena, San Marin, Novato and a couple of teams that might manage to get eligible (Tamalpais?, Drake?). I don't think Marin Catholic's slate of wins is any more impressive than Moreau's. Now Cardinal Newman, if they win out, will have wins over Rancho Cotate, Windsor, Casa Grande and Del Norte (who's looking like a 5-5 team this year). If they win out, I think they have a better case (though I don't know if I call it a shoo-in).
