I'm not going to do all the matchups because simply that would take too long. Instead I'm to do the NCG, Fiesta bowl matchups that would be more exciting to watch and who OU might play.
Matchup 1: BCS NCG
Alabama vs Oregon or Alabama vs Kansas State
Personally I would rather go with Alabama and Oregon not only because I believe that it would be a better game but also because of my disbelief in Kstate. Don't get me wrong kstate is very good this year and definitely deserves to win the big 12 championship but I also dont believe that are a NC caliber team. Yes they won against OU and OSU but lets be real for a minute their wins against these two teams was not due to them it was due to OU and OSU shooting themselves in the foot with turnovers. You cant really give them quality wins against TTech and WV because they have both shown they were nothing more than preseason hype. Unfortunately IMO Kstate is good but I think if they played Alabama or Oregon the game would be decided by in the 1st quarter.
Matchup 2: Fiesta Bowl
Kansas State vs LSU or Kansas State vs Florida or Kansas State vs Georgia
Honestly I believe Kansas State and Florida will be the better matchup but I think Kansas State plays Georgia because Georgia would own the tiebreaker between them and Florida. Whether this is in the fiesta bowl or not still remains to be seen because of the way the bowls pick their teams and since the Fiesta Bowl has the NCG they get the last pick when it comes to the automatic qualifiers this year and the bowls only choose who will be more popular(stupid right, the bowls should have to take the next opponent down the line so it would be 1 vs 2, 3 vs 4, 5 vs 6, and so on).
Matchup 3: A BCS Bowl or Cotton Bowl
Oklahoma vs LSU or Oklahoma vs Louisville or Oklahoma vs Nebraska
It pains me to say this but out of all the top teams OU will probably be the last option for a BCS bowl unless its against the Big East winner or Nebraska. I think we would play LSU in the cotton if we dont go to a BCS bowl. If OU plays Louisville then that is an easy win and it would also be the least watched post season game so thats why I don't think that one will happen. If OU plays Nebraska that will be the most watched game in the post season because of the history between the two.
All of this is just my opinion of what I would like to see happen at this point in the year and I am in no way saying that this will happen. Sound off and tell me what you think and what matchups that you would like to see in the post season.
