There is absolutely no OBJECTIVE way to determine strength of schedule, none. Let's say a team loses to a 9-1 team, who is to say that 9-1 team isn't one of those "goat herder" schools people keep mentioning? Who determines if that is a good loss or not? The Harbins is objective and rewards WINNING. It also rewards winning against schools that win. It's a great system. Quit ing and win your games. Too much if our society rewards losing, we don't need to add that to football in Ohio.
If your team didn't make the playoffs because of your "tough schedule" then what do you think will happen in the playoffs? I promise you no team missed the playoffs that would have won a state championship. Every team controls their own destiny, just win. Again, just win. Pretty simple philosophy.
