See, that's the problem with evaluating potential matchups based upon score comparison. You think Folsom would have struggled with Antioch and San Ramon Valley to the degree Pitt did?
Tracy faced SRV, St. Mary's and Folsom this season losing by 20, 28 and 35 respectively. By score comparison logic, a Folsom v. St. Mary's game should have been pretty close. But we eventually saw that matchup in the postseason and it wasn't close at all.
So what can you conclude from Pitt only beating SRV by 9 who beat Tracy by 20 who in turn lost to Folsom by 35?? Absolutely nothing --- as evidenced from the Tracy-St. Mary's-Folsom example.
These teams simply can matchup much differently based upon their unique strengths, weaknesses and varying level of play over the course of a 10-16 week season.
I'd take Folsom over Pitt by 2-3 scores and Central over Pitt by a score or two but score comparisons aren't going to prove or disprove that opinion. For all we know, Pitt d-line could dominate the game and Folsom would lose by double digits.
