Made in R using these packages: cfbfastR, ggimage, tidyverse, gganimate, ggthemes.

Edit: data from ESPN using cfbfastR package

Explanation of FPI efficiency: "Team efficiencies are based on the point contributions of each unit to the team's scoring margin, on a per-play basis. The values are adjusted for strength of schedule and down-weighted for "garbage time" (based on win probability). The scale goes from 0 to 100; higher numbers are better and the average is roughly 50 for all categories. Efficiencies update daily during the season." It's basically an advanced metric designed to measure offense and defense.

Any numbers on a line of best fit and how well the data matches it? Just curious because the correlation here looks a lot weaker than I would have guessed it would be.

Indeed it is weak. Slightly positive correlation with adjusted R-squared of .1
