This thread has been a good read. I guess I'll chip in now. I've played against Riverdale and have all the respect in the world for them. I think they have proven everything they have to, to anyone who cares. Yes, it'd be fun to see how they match up against Robert E. Lee or Trinity but to be honest, in the grand scheme of things concerning their program, staff, school board and most importantly, the players (who are also students, mind you), what they have to gain out of playing out of state powers, just may not balance out for them. The effort by parents and boosters to provide transportation may not be deemed worth the respect gained by the trip itself. The players, in December after having what are usually great seasons, probably will not feel any better or worse about their big fat rings wether or not they played out of state teams for their non region games.
In short, I'd say it is just a matter of opinion and value. I think everyone on this thread has had valid points and no one is wrong, and that's what makes a great thread.
