How does Notre Dame go from 20th to 19th after loosing to an unranked team?? And how does Tennessee go from 7 to 13th after loosing to unranked University of Florida and 10th ranked Uconn?? And how on God's green earth is Iowa still ranked.
I'll give it a shot.
ND beat NC State who was ranked #3 at the time so that's why the FSU loss impacted them less. Had they beat FSU they could have had a big jump in the polls.
Tennessee was the 7th ranked team and I believe as high as #5 until the loss at Auburn. The Florida loss, while unranked at that time, off sets the slide as the Gators are now ranked and probably should have been last week. I expect if Tennessee can't right the ship, they will continue the descent. They have Missouri and Vandy this week so it can go either way. The tigers could get them.
Iowa had two losses to ranked teams last week (Ohio State and Michigan<who climbed to #4>). I guess the voters felt they were still a top 25 team since both losses were good games and ranked opponents.
Also South Carolina lost to unranked Missouri and remained #1 a few weeks ago. Not all losses are equal unfortunately.
Thats just my non-voting 's explanation.
