The committee's job is to evaluate the teams on the field, not their conference affiliation. Florida State went 13-0 against a full ACC slate last year and was evaluated just fine. Imbalance has always existed, with some SEC West schedules being far tougher than others for years. The real issue is whether a team can dominate their schedule, and the metrics like game control and scoring margin already account for that. If a team is truly elite, their performance against their given schedule will show it in the data every single time.
