It was (un)lucky number seven for many college football teams this weekend, as seven ranked teams lost in Week 7 of the season, including three schools ranked in the top ten of the Coaches' Poll. Via USA Today's Facebook page:

Hey, we finally joined Facebook!

Stanford, Georgia and Oklahoma each see dramatic drops in their status, as the three top ten teams lost (including losses to unranked Utah and Texas for Stanford and Oklahoma). Missouri, who beat Georgia quite easily Saturday afternoon, finally enters the Coaches' Poll after their undefeated start was snubbed for weeks and weeks.

LSU moves into the Top Ten after an ugly win over Florida, and Michigan and Northwestern both fall after losses to unranked teams. Not much movement for Florida and Washington, however, who both lost to highly-ranked opponents.

The Coaches' Poll is supposedly voted on by coaches, who are busy coaching their teams during game day, but is instead most likely voted on by people in the media relations department, who are also busy working with their teams on game day. Regardless, the poll counts in the BCS rankings.
