Rankings
Every poll release of the season, with what changed since the one before.
The polls are a vote. Team Strength is the measurement: every team rated from the play-by-play against the opponents it actually faced, with strength of record and strength of schedule beside it.
Polls list whoever the voters ranked, including teams outside the Power 4. The site’s “ranked” filters follow the College Football Playoff ranking once the committee releases one that season, and the AP poll until then.
