Alabama, Florida, Oregon, Kansas State, Notre Dame and Ohio State are all undefeated. But what about the lesser known unbeaten teams of the FBS? How likely are they to remain spotless?

5. Louisville (7-0) »

In the weak Big East, the Cardinals haven't faced a ranked team. With four wins by seven or fewer points, Louisville is due. The toughest games left are with Cincinnati on Friday night and at No. 18 Rutgers on Nov. 29.

4. Mississippi State (7-0) »

Its three SEC wins have come over teams that are a combined 0-14 in the league. Mississippi State is the only SEC team that has yet to play a ranked foe. Now come consecutive games at No. 1 Alabama, against No. 22 Texas A&M and at No. 6 LSU.

3. Oregon State (6-0) »

The impact of wins over ranked teams UCLA and Wisconsin has faded. Neither seems as formidable now. The Beavers play at No. 19 Stanford on Nov. 10 and host No. 2 Oregon in the "Civil War" two weeks later.

2. Rutgers (7-0) »

It has won all of its games by at least eight points. If the Scarlet Knights go undefeated, they will earn it, finishing at Cincinnati, at Pittsburgh and hosting Louisville in a span of 13 days.

1. Ohio (7-0) »

When the Bobcats opened with a win at Penn State, it seemed more an indictment of the Nittany Lions. But seven weeks later Ohio is still perfect. The Bobcats will close at Kent State (6-1) likely to settle the MAC East.
