Which conference is the deepest is open to debate.

But up at the top, the Big Ten rules...at least for now.

The latest AP poll is out and there are four teams from the Big Ten ranked in the top ten:  (2) Ohio State, (4) Michigan, (8) Wisconsin and (10) Nebraska.

The SEC has the most teams in the Top 25 with three in the top ten:  (1) Alabama., (6) Texas A&M, (9) Tennessee, (12) Ole Miss, (18) Florida, (22) Arkansas and (23) Auburn.

Four teams from the "group of five" have cracked the rankings:  Houston dropped to #13 after their loss to Navy, undefeated Boise State is #15, and two new schools have entered the poll:  Western Michigan at #24 and Navy at #25.
