LOL. Seems to have worked for them; Plano produced Earl Campbell, as I remember!
But, if you think about it -- if there are 5000 kids in a school, there are still only 12 (or 24 if you count both offense and defense) spaces on the football team. And there are only 5 starters on the basketball team, and 9 starters on the baseball team.
What are the rest of the 2500 boys doing in their spare time?
There were only about 350 boys at Strake Jesuit when my oldest son started there. Every boy was required to be on one of the sports teams at the time. They hauled my kid out of the typing class to run cross country! Four years later, he placed second in the state in the Texas Catholic School Boys League his senior year. His record was still standing at least until a couple of years ago!
During my oldest son's junior year, 1977-78, Jesuit won first in the State (Texas Catholic School Boys League again) in every sport -- Football, Cross Country, Basketball, Baseball, Golf, Track, Tennis, & Soccer.
Some of those kids went on to have great sports careers, and some of them were never heard of again. But, they had the chance to compete and achieve something memorable at a young age. They would never have had a chance to do anything at Dulles. One of my son's classmates turned down a pro- football contract to go to Med School.
The other advantage is that my two sons received an education the equivalent of the Honors classes my daughters were getting at Dulles HS. The Jesuit basic education was as vigorous as the Dulles Honors classes. The Dulles Honors classes, however, were limited to 30 kids -- Total! My sons would never have been chosen out of their 5000 schoolmates.
Sending the boys to Jesuit was expensive and very time consuming for me -- I had to drive them and pick them up at least 3 days per week for about 8 years. But, it was worth every penny I spent and every hour I sat in traffic on the Southwest Freeway! I credit their Jesuit education for all their success.
Earl played at Tyler John Tyler HS (but his senior year State Championship team did beat Plano handily in the 1st round of the playoffs). Strake is a fine school, I had numerous friends from Meyerland/Bellaire (Holy Ghost kids) who went there or to St Thomas. Your boys are very fortunate to have had your sacrifices enable them to go there (I thought about the drive from where y'all lived, not an easy commute!).
