Will we have an undefeated national champion?
The debate is currently raging if anyone will finish the season undefeated. #1 Oregon State has 2 difficult contests left, #12 Utah and #4 Oregon; and if they win them and go 12-0 in the regular season Utah or USC will most likely be waiting for them in the Pac 12 championship game.
#2 Boise State has an easier road, their most difficult game left is Fresno State (8-1) but that game is in Boise where the Broncos have lost only one game since 2005. If the Broncos finish undefeated, they still have to win the bowl game they are in, which will most likely be the BCS national championship.
#25 Idaho is the darkhorse, but due to the scheduling woes the WAC had this year have given Idaho the weak schedule they need to go undefeated. However, Idaho has no shot of making the national championship. Even a win over a highly ranked Notre Dame team is not enough to propel you to the BCS National Championship game with all those FCS and Sun Belt opponents.
Big XII talk
For the second straight year the Big XII is one of the most loaded conferences with Oklahoma, Kansas, Missouri, and Texas A&M all top 15, and every one of them legit contenders for the Big XII Title. Most likely the title will belong to either A&M or the winner of the Kansas/Missouri battle. Oklahoma already has two conference losses, and Kansas and Missouri are both undefeated in the Big XII. In order for Oklahoma to win the Big XII, either Kansas and Missouri both have to drop three conference games, or a 3 way tie occurs if Missouri and Kansas both drop two conference games.
A&M can win if they defeat Missouri, and Kansas drops two games; or if A&M beats Missouri and Missouri defeats Kansas and they end with a three way tie, one A&M might win due to the BCS rankings rule.
But mainly everyone expects it to come down to Kansas & Missouri. A&M/OU cannot afford to lose, whoever does this week is almost completely out of the race for the title, and therefore the Fiesta Bowl bid. If Kansas and Missouri win out, the Border War will be a matchup of most likely two top 8 teams, a nice tribute to 2007 when it was #2 Kansas vs #4 Missouri.
If Kansas or Missouri go 11-1, and either OSU or BSU lose, then they have a shot at the national championship game.
SEC/Big 10
The SEC has 5 teams ranked like usual, and a team in the national championship banter like usual, but for once they don't control their own destiny. #3 Auburn has to battle #23 Ole Miss this week and eventually 1 loss UGA, possibly facing UGA again in the SEC Championship. Besides UGA and Auburn there is no title contender in the SEC this year, and it is highly unlikely an 11-2 Auburn or Georgia team will play for the crystal football.
Despite having several ranked teams, including 1 loss Iowa, the hopes of the Big 10 rest solely on #5 Illinois's shoulders. The Fighting Illini have the best shot at making the BCS Title game, as even though the Michigan State Spartans are a top 10 team, they already have three losses and most likely will not get a fair shake at the title game even if the win the Big 10.
