I'm not sure all of the rules regarding the bowl games but here's what I know for sure, based on who I think will win in conference Championship games.
Ohio State will play West Virginia in the National Championship game.
LSU will play in the Sugar Bowl. I say will because I think they will win the SEC.
USC will play in the Rose Bowl... probably against Georgia since I think Rose Bowl would get first pick and there's absolutely no reason for them not to take Georgia considering how well they travel and would be ranked #3.
Virginia Tech will play in the Orange Bowl. I think they beat Boston College this time around.
Oklahoma will play in the Fiesta Bowl, since I think they'll win the Big XII.
I think, faced with the decision to pick Mizzou or Kansas, Missouri plays in a BCS Bowl, leaving Kansas the odd man out from the Big XII since a conference can only have two representatives. I think the Orange Bowl gets the next pick, and at this point, all better choices are already locked into bowl games, so the Orange Bowl takes Missouri.
The Fiesta Bowl gets next at-large pick, and they turn down the opportunity to pit Oklahoma against ANOTHER WAC team because Arizona State is guaranteed to travel better than Hawaii because, well, they don't even have to travel!
The Sugar Bowl, getting the last pick, takes Hawaii, who beats Washington in the final week.
So here you have it... winners in bold.
Championship - West Virginia vs. Ohio State
Rose Bowl - USC vs. Georgia
Orange Bowl - Virginia Tech vs. Missouri
Fiesta Bowl - Oklahoma vs. Arizona State
Sugar Bowl - LSU vs. Hawaii
