How can anyone say the B12 is weak this year? The Big10 has several teams that a waay overrated where they are in the rankings...that is the case EVERY year. There are a whole bunch of gimmes in that league. There are not in the B12. If Oklahoma wins out I don't see how they get left out of the playoffs. If they do the system is a total joke.
Then you have failed to fully understand the system. The Big-12 has been weak for three years. While it is a bit of the tin-foil hat category, there are those that suspect the Big-12 is being punished for not playing by the same rules as the other conferences, i.e., expanding to 12. There are 4 slots in the main stage and 5 conferences plus Notre Dame if they can be worked in at all. Notre Dame is very likely to only have one more game to challenge them in Miami. They have a very good chance of winning out and finishing 11-1, if they do, they are in. That leaves 3 slots and that will mean even a 1 loss Oklahoma is out of luck. Ohio State, Alabama, Wisconsin, Georgia, at least 2 of those are going to be in. That is 3 of the four slots. Oklahoma has to compete with a lot of 1 loss teams and with a weak Big-12 resume, it will not help them.
