We may start to see this every weekend. Just a few weeks into the college football season, and already there’s been constant change within the rankings.

This weekend, six teams that were ranked in the Associated Press Top 25 fell to unranked opponents, which will undoubtedly result in some significant changes in this week’s polls. Two other ranked squads fell, as well, but both lost to higher-ranked opponents.

Oklahoma suffered a second-straight loss, this time to Iowa State while Texas fell to in-state rival TCU, squashing a lot of College Football Playoff hopes for the Big 12. Arkansas snapped its three-year SEC losing streak to Mississippi State and Tulsa ended the nation’s second-longest home-game winning streak by upsetting UCF.

Pitt lost to NC State an Memphis came up short to SMU. Below is a look at the six ranked opponents that fell this weekend:

  • TCU def. No. 9 Texas — 33-31
  • Tulsa def. No. 11 UCF — 34-26
  • Arkansas def. No. 16 Mississippi State — 21-14
  • Iowa State def. No. 18 Oklahoma — 37-30
  • NC State def. No. 24 Pitt — 30-29
  • SMU def. No. 25 Memphis — 30-27

All six games were decided by one possessions, with the largest margin of victory coming by 8 points. It should be interesting to see what this means for the latest rankings.
