NCAA Football Power Rankings, Week 4

Notre Dame lost their game and their #1 ranking this week, falling down to #9. But, Ohio State couldn't quite take over the #1 spot with their win, rising up to #2, right behind Penn State. Missouri is surprisingly ranked #3. They're playing #79 Vanderbilt this week, so even a win may bring them down due to a weakening schedule. This reminds me that I've thought about making a more "predictive" set of rankings as well, which would take into account the teams' future scheduled games, which would make the strength of schedule fluctuate a little less through the season.

I mentioned my new data source allowing me to fix previous week's errors. There was again one game they had wrong last week. It would appear the Howard vs Hampton game was entered before it ended, so the 35-34 victory for Hampton showed as a 34-28 loss. I thought maybe it was a last-second victory, but the winning TD and PAT came with just over 3 minutes to go in that game, so I'm not sure what happened. Regardless, it did not affect the top 46 teams last week, and otherwise only swapped around groups of 2 or 3 teams in a few places. The good news is that in past years, this error would have carried forward for the rest of the season, because I only put the new games into my software each week, but now the full season so far is used, and also checked against the previous week for differences.

There are now 27 undefeated teams left, down from 39, and there are 5 winless teams, down from 7. Buffalo lost but still got out the cellar because Sam Houston State is the new #133.
