So then fix the ranking process.
That has nothing do with the format.
It’s not the “process”. It is a ranking system that involves people, who tend to overvalue brands they are familiar over better performance on the field by lesser known entities.
Notre Dame was a preseason top ten team and lost their first two games, yet stayed in the top 25 and started working their way back up the rankings.
An “upstart” team that lost its first two games and had a remaining schedule as week as Notre Dame’s likely has to get to 5-2 or 6-2 before they even hit the “Also receiving votes” list.
