Oregon, which was the only Top 25 team to lose Saturday, dropped from 11th to 16th.
The Top 25 went 23-0 against unranked teams to open the season, leaving the rankings mostly unchanged: No. 1 Clemson and No. 2 Alabama are at the top of the first regular-season AP college football poll of 2019.
The Tigers received 54 first-place votes out of 62 in the media poll, up two from the preseason. The Crimson Tide received the remaining eight.
The top seven teams in the preseason rankings held their spots Tuesday. Clemson and Alabama were followed by No. 3 Georgia, No. 4 Oklahoma, No. 5 Ohio State, No. 6 LSU and No. 7 Michigan Wolverines. Notre Dame moved up a spot to No. 8, and Texas was ninth. Florida slipped three spots to No. 11.
Another record for Alabama. The Crimson Tide are ranked in the top five for the 56th consecutive week, dating to Nov. 8, 2015. That breaks a tie with Miami, which went 55 straight weeks in the top five from Oct. 8, 2000-Oct. 26, 2003.
MOVING IN, BUT NOT OUT
No. 24 Boise State was the only team to move into the rankings this week, but in a quirk, no team fell out. There was a tie at No. 25 between Nebraska and Iowa State. The Broncos are ranked again after rallying from 18 points down to beat Florida State on the road Saturday.
The last time there were 26 teams in the Top 25 with a tie for the final spot was Nov. 18, 2012. The last time a full schedule of college football was played and no teams fell out of the rankings was Nov. 6, 2016.
IN CASE YOU WERE WONDERING
There have been three times since the AP poll expanded to 25 teams in 1989 that no ranked teams lost during a regular-season weekend schedule. In 1996, Top 25 teams went 11-0 leading into the second regular-season poll. The Top 25 had two undefeated weeks in September 2004, going 18-0 the opening weekend of the season and 19-0 a few weeks later.
The Southeastern Conference has four teams in the top 10 and six in the top 12. The last conference to represent half of the first dozen teams in the rankings was the SEC on Sept. 7, 2013: No. 1 Alabama; No. 6 South Carolina; No. 7 Texas A&M; No. 9 LSU; No. 11 Georgia; No. 12 Florida.
