For right now, yeah. But all associations have to do is have a rule that member schools cannot play schools not associated with an association.
Trinity Christian was in TAPPS, which is the big Texas independent school group until they were kicked out (some say sour grapes by the association) last year.
All I’m saying that in an era where schools don’t want to have huge travel expenses and want to save money, what Trinity Christian is doing seems counterintuitive.
Heck, UConn moved back to the Big East because their football aspirations & change in conference affiliation to the American were too much for the university’s budget
