KU has appeared in every poll in every year except 2006 (5 of 19) and 2009 (11 of 19)
Not only is KU frequently in the polls but we are usually near the top. Counting 25 points for 1st, 24 for 2nd etc, here are the top teams since 2004 in points.

Just as a pure trivia, there have been 122 teams who have appeared in the top 25 during this period. During this period, the other 9 teams currently in the Big 12 have amassed 8888 points. Therefore KU has amassed 36% of the total points of the Big 12 in terms of AP Polls. Texas is 2nd at 15.6%. Kansas has obviously dominated the Big 12 in terms of AP Poll appearances and along with Duke, they have dominated the nation.
