Successive victories over Oklahoma and Arkansas have convinced voters that Texas belongs among the Top 25. Two successive losses also convinced them that Air Force doesn't.
Following a weekend of upsets, those are among the most dramatic changes in the Associated Press college football poll.The Longhorns, who shocked Oklahoma two weeks ago, did the same to then No. 7 Arkansas on Saturday by a 24-20 score to move into the ranked teams for the first time this season at No. 24.
Clemson was the other new face in the Top 25 this week, moving back in after a week's absence at No. 22 following a 30-10 whipping of previously undefeated No. 12 North Carolina State.
Meanwhile, Air Force lost for the second straight week, 27-9 to Texas Christian, to drop to 6-2 for the season and out of the Top 25. The Falcons, No. 19 last week, had won their first six games before losing to Notre Dame 41-27 and to TCU.
Oklahoma, No. 25 last week, also dropped out, although the Sooners beat Iowa State 43-40.
There were plenty of other shakeups in the Top 25, although Nos. 1 through 5, led by Notre Dame, remained intact in the weekly voting by the nation's sports writers and broadcasters.
The Fighting Irish, who have held the top spot since winning the Kickoff Classic in August, won their seventh game of the season and 19th in a row overall with an exciting 28-24 victory over Southern California.
The Irish garnered 56 of the 60 first-place votes and 1,496 points overall. Miami, idle last week, held the No. 2 spot with 1,424 points, including three first-place votes. Colorado, a 49-17 winner over Kansas, was again No. 3 with 1,379 points, including one vote for first.
Nebraska, which beat Oklahoma State 48-23, remained fourth, followed again by No. 5 Michigan, a 26-12 winner over Iowa.
The remainder of the Top 10 includes No. 6 Alabama, No. 7 Pitt, No. 8 Illinois, No. 9 Florida State and No. 10 Southern Cal.
Alabama moved up four spots following a 47-30 victory over previously unbeaten Tennessee, which was No. 6 last week. Pitt moved up one spot after an idle weekend and Illinois jumped five places after a 14-10 victory over Michigan State. Florida State moved up five after taking a 22-14 decision over Auburn, No. 11 last week. And Southern Cal dropped one spot after its loss to Notre Dame at South Bend.
The rest of the Top 25 includes No. 11 Tennessee, No. 12 Houston, No. 13 Arkansas, No. 14 Penn State, No. 15 West Virginia, No. 16 Auburn, No. 17 Arizona, No. 18 Brigham Young, No. 19 Florida, No. 20 North Carolina State, No. 21 Texas A&M, No. 22 Clemson, No. 23 Washington State, No. 24 Texas and No. 25 South Carolina.
