LOUISVILLE, Ky. (WDRB) – We have reached the one-third mark of the 2012 college football season, but the number of unbeaten FBS teams has been reduced to considerably less than one third.

It's a list of 26 teams – and half are from two conferences, the Big 12 (7) and the SEC (6).  That makes it a perfect time to look at the 26 teams and guess when each will take its first defeat.

There's a solid chance, by my calculations, that seven unbeatens will fall this weekend. And my scenario, Louisville has a reasonable chance to take advantage of its user-friendly schedule and become the last unbeaten.

(Disclaimer: Unless, of course, the Cards lose earlier.)

We are guaranteed to lose at least two unbeatens this weekend. Texas Tech (3-0) visits Iowa State (3-0) and Baylor (3-0) visits West Virginia (3-0).
