Clemson goes 15-0, beats everyone in their path including the only other undefeated team, but we need to change the format to find a "true" champion. Give me a break. If that's your answer just go back to Poll Champions and you can whine when there's a split in the AP/Coaches Poll.
To answer some of your assumptions:
-Yes, I thought Georgia would beat Texas - motivation can be a hell of a difference maker though.
-Yes, I thought Bama would beat Clemson - closer game than the 44-16 blowout indicates, but very surprised Clemson won and happy they won in that fashion.
-Yes, Clemson would have made the Playoff if they lost to Syrcause because Lawrence was injured during the game - injuries matter, even if he didn't play all that well prior to the injury.
-Yes, OSU would have made the CFP if MSU didn't beat Michigan, but OSU would have also had to beat Iowa in the B1G Championship Game. Buckeyes probably favored there but it's an extra game to potentially slip up. But like you said, if Ohio State was the best team, they beat a couple of backup QBs on their home field.
