Obviously doesn't apply to all of their players but a lot of them have already demonstrated a kind of mercinary attitude coming to Mullen in the first place. Some of their kids are products of the Catholic school system and Catholic families for whom Mullen was the logical HS of choice regardless of athletics.
A lot more of their players are not products of the Catholic school system, not even Catholic. They are there because they were persuaded (recruited) to attend Mullen and participate in sports. They have already shown that ties to their neighborhood schools, their friends, etc. are secondary to them. They go across the city to go to HS, no big deal to leave the state for a better deal in college in their minds
I qualify this as a broad generalization that doesn't apply to all kids. CU has had some great kids from Mullen as has CSU, AFA, and the smaller schools in state but the joke about Dave Logan turning down the UNC job because of the lower recruiting budget has some element of truth.
Mullen doesn't recruit. They are the best team in the state and if you want to play for the best you go to the best. Plus their education is 2nd to none. Any kids would be crazy not to want to play for them. I dont believe that leaving your local under par (both sports and education) school, to better yourself has, has any impact on your college decision. IMO.
