Teams have no say over when conference games are scheduled and are limited as to what dates are available to schedule non-conference games. Nothing about how many games a team plays says anything about how good they are. You can only play 11 games except in certain circumstances, none of which a team should cause a team to be rewarded for simply playing the extra game. While the higher rated team at game time may win, it will not be because they're the higher rated team. The goal is to be ranked highly at the end of the year and teams should be judged by year-end ratings.
Nothing is more irrelevant in college sports than last year.
This year's team has no control over last year's ratings. Obviously they impact results, but they're not quantifiable. Also not reliably reported and may change during a game. Yes, they appear in a box score, but sometimes even those get changed after the fact. Teams have some control here.
