FEI ratings are based on possession efficiency, and each drive and possession change event has a measurable impact on the final score. As might be expected, the average value of starting field position is the same as the average value of a given first down series from the same field position. First downs are statistically similar to the start of unique possessions.
So while I'll be paying close attention to overall drive efficiency throughout the title game, efficiency per first down series will reveal an even more refined view of the championship battle between Alabama and Notre Dame. The charts above represent the first down series success to date for both teams.
