Undefeated After Week 5

Thanks for playing, Houston, Michigan, Texas A&M, and UCLA. Five weeks into the season, and already two BCS conferences are without an undefeated team (ACC and Pac-10).

We are now down to 13 FBS teams that are undefeated, 12 of which are in the AP Top 25. A maximum of 6 teams will be able to finish the regular season undefeated.

Here is a conference-by-conference breakdown of the undefeated teams, with the number of possible undefeated teams in parentheses:

Big 12 (1)
North
-Kansas
-Missouri
South
-Texas

They all play each other, so only one can possibly emerge undefeated.

Big East (1)
-Cincinnati
-South Florida

They play each other, so only one can possibly emerge undefeated.

Big Ten (1)
-Iowa
-Wisconsin

They play each other, so only one can possibly emerge undefeated.

Mountain West (1)
-TCU

SEC (1)
East
-Florida
West
-Alabama
-Auburn
-LSU

If Florida wins out, that means that LSU is not undefeated.
If Alabama wins out, that means that Auburn and LSU are not undefeated.
If Auburn wins out, that means that Alabama and LSU are not undefeated.
If LSU wins out, that means that Alabama, Florida, and Auburn are not undefeated.

Also, because the winner of the East faces the winner of the West in the SEC championship game, there can be only one undefeated SEC team.

WAC (1)
-Boise State
