They only legitimate way to determine the "national champion" is to have a playoff system like every other sport, including all levels of NCAA football. Every conference winner and a few at large teams should decide it on the field. Pretty simple. But won't happen.
I agree and your right it won't happen. The Big-10 has no championship game and doesn't want one. Notre Dame (which everyone loves) will never join a conference. Just think about how boring it would be to see the SEC champ and another top 5 SEC school run the table through that system and end up playing each other again in the champioship. Not to say it's not legit, but it's all about $$$
Just look how bad everyone (reporters, sports talk shows, radio) wanted Michigan to get a rematch because they felt they had the best shot at beating Ohio State. Or the people who wanted USC there instead.
I love the SEC, but I know it won't happen simply because of REGIONAL generated $$$. You'll lose west coast, midwest, some eastern and northern ratings big time.
I'm still trying to find the other Sears trophy for the 2004 BCS championship that's actually located Baton Rouge, Louisiana that was converted to an AP Poll "shared" title with the feel good "west coast tv coverage"team USC from 2004 that was supposed to be irrelevant because of the BCS system.
Why wasn't USC vs LSU played out that year? REGIONAL COVERAGE. It was better to play OU vs LSU in the sugarbowl for the south, southeast and play USC vs Michigan in the rosebowl for the entire westcoast and north, northeast coverage than play LSU vs USC for the "TRUE" title game (since they knew their could be a possible split if the didn't play obviously, but the BCS was supposed to eliminate this...LOL!!) also they would have lost the Rose bowl $$$ because the BCS title was to be played at the Sugar, and they knew they'd lose alot of $$$ on a Michigan vs OU Rose bowl in pasadena (

) yeah that wouldn't fly with west coast coverage.
It's all about $$$. Which is how auburn got shafted. They were considered boring, not ready...etc. Well they ran through the SEC, won the SEC title..what more do you have to do. Wasn't about that, it was about coverage. The BCS Title game was at the Rose bowl that year, so you'd lose $$$ at the sugar bowl since that game would or could have been OU vs some other team and not an SEC team.
Plus not to mention OU got their a$$ smashed like 60-10 or some sh*t. What a great game.
I'm all for the playoff system, but it won't happen man.
