I don't watch college football anymore these days. The whole ranking "system", and especially the "national" championship title is so skewed, biased, and unrealistic that it no longer holds any meaning at all. Without a true playoff system, it's all just one big east coast popularity contest anyway. I don't see how a voting system can be anything but.
And before you spend the energy to come up with some witty remark about a Washington state team, know that I'm no fan of those teams either. They're bad, period. And no amount of votes will change that. But at least we'd know exactly where they rank if there were a true, honest system.
Just my opinion. Like I said, I don't follow it anymore, so what does it matter anyway?
