The Top 25 went 23-0 against unranked teams to open the season, leaving the rankings mostly unchanged with No. 1 Clemson and No. 2 Alabama 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 in the poll presented by Regions Bank.

The only Top 25 team to lose was Oregon, which slipped to 16 after dropping a thriller to Auburn. The Tigers moved up to 10th.

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. Notre Dame moved up a spot to No. 8 and Texas was ninth. Florida slipped three spots to No. 11.

No. 24 Boise State was the only team to move into the rankings this week, but in an odd quirk, no team fell out. There was a tie at No. 25 between Nebraska and Iowa State. 

The Southeastern Conference has four teams in the top 10 and six in the top 12.
