It does raise an interesting question though. If two teams are hand selected by a panel to play for a national championship, is it more likely to introduce bias into the process than if four are (or eight ... Or sixteen)?
i’m a college football purist and could care less about any playoff system but there’s bias in everything, just like everything is racist...
if there were eight teams in the playoff the ninth team would be b!tchin about bias, and the 17th team would b!tch if it were a 16 team draw....
there’s what- 68 teams in the NCAA BB bracket and someone is always crying bias about not making it...
