No, Massey cannot be debated in the same way as the committee approach. One is set in stone before the competition begins. The rules don't change during the game. The other presents not only inherent human biases (favoritism), but also blatant corruption DURING THE COMPETITION (season). Why can't you understand this? What is it with you?
We would all like your solution. That is NFL-like. But this is college -- limited complex, disparate data that, due to the inability to form a true league, some sort of systemic approach to identifying a champion must be in place. (Or we can agree that there can be no "champion.")
Consider the World Golf Rankings -- a system that blends disparate tours and leagues from all over the world. A committee might have made up the rules to rank the players, but it doesn't sit down each year and by discussion decide who is #1, #2, #3, and so on. It decides the system and then lets the system take its course. The World Golf Rankings then play a role in some tournaments. Same with Fed Ex Cup points. A committee doesn't decide who gets into the golf post season. A committee decided beforehand what the system would be. They don't decide who deserves a playoff spot each year. The system decides it.
So it must be for a problem like College Football, if we truly want to be fair and honest about it.
