I usually try not to "fall into the trap", but I have some time. We started our Mater Dei experience in 1983 as part of the Cluster system. They cursed us, spat on us, berated us and beat the crap out of us for many years. After 8 straight losses over 19 years, we finally turned the tables, winning six of the next ten.
Yes, they have a bigger roster. And no they don't have kids who would rather play video games than excel at school and extracurriculars. Their parents don't pay tuition for them to be slugs. While the public school enrollment is increased with a diversity of kids who will never play anything. (If we could only ship them to Sullivan or Jasper!)
Granted, over the years Mater Dei has lost some kids to the glitz and glamor of other schools. But the tradition which is Mater Dei will never die. So if you want to beat them stop worrying about the number on the sideline and focus on the 11 guys on the field. And by that I mean YOUR 11.
Stop the run, change coverages, disguise coverages and "Run the damn ball!"
