Over the past 10 years, on average, a little less than two teams that start the season ranked in the AP top 10 finish the season unranked. There are currently four preseason top-10 teams out of the poll.
Washington and Wisconsin became the latest. The Huskies were No. 15 last week but lost to California 12-10. They started the season No. 6. The Badgers, No. 4 in the preseason poll, fell 31-17 at Northwestern.
Also on the outside of the rankings after starting the season with lofty expectations are Miami (preseason No. 8) and Auburn (preseason No. 9). The last time four preseason top-10 teams finished unranked was 2002, when Tennessee (preseason No. 5), Florida (No. 6), Washington (No. 9) and Nebraska (No. 10) flopped.
