We’re back and (hopefully) better than ever. Let me know if anything on the relaunched site is wonky or anything, and let’s get the 2025 college football data season rolling: bcftoys.com

Starting field position differential is an interesting "core" metric. I've found that it does have a positive relationship with team strength, but not nearly as strong as offensive and defensive efficiency metrics do.
bcfremeau.bsky.social
Interesting to me that 7 of 12 core metrics are "raw" unadjusted statistics and five are "opponent-adjusted" (as in, calculated relative to opponent averages)
bcfremeau.bsky.social
But I also have more questions!
- Relative scoring offense and scoring defense; I'm curious if these metrics are calculated with *all* game points scored, or only those scored on offensive drives
- Same with points per possession (off/def), yards per point, and plays per point

Love digging into these articles every year on the committee selection process, and this one has some intriguing details about the 12 metrics used as the "bedrock of team comparisons".

Averaging two teams' GR percentiles in each game as a way to rank the year's best so far...

.913 Ohio St 14, Texas 7
.910 Oregon 30, Penn St 24 (2OT)
.899 Alabama 24, Georgia 21
.868 Georgia 44, Tennessee 41 (OT)

Both teams 80th+ percentile GR in each. Passes a sniff test?

What I'm sure I can do better at is bridging the gap for those encountering "analytics" they don't immediately understand. There have to be better entry points than just "look at this list of teams, now love/hate/share it".

I *think* I do a fairly decent job at this stuff with FEI but please let me know if I’m missing any marks:

- ratings are clear about what is being measured
- supporting data is there to explain why some ratings might not make intuitive sense

FEI without preseason weights are still pretty wonky at this point because of limited data. Oregon would be 10th, for instance, having just defeated #29 Penn State. Top 5 would be:
1. Indiana
2. Miami
3. Notre Dame
4. Texas Tech
5. Alabama
