As far as private high schools in Colorado go, there are only a few that could seemingly compete in the same league as Valor and those are Regis and Mullen (and Mullen would get beat by Valor 40-3 in all likelihood). There just aren't enough private schools in CO to create a whole new league with their own playoff tournament.
That's why the Dave Logan move to creek was a big one. Even though it is fighting fire with fire at least a public school beat them in the championship. An even bigger next step would be getting Douglas County back to where they were before Castle View was built and their enrollment went down. Grandview and Cherokee Trail are going a great job too but it is important that schools like Columbine, Bear Creek, Fairview, and Arvada West get back to where they used to be or in the case of Fairview and Columbine, continue what they are doing.
