For five years (2006-2010), the Pac-10 football teams played a round-robin conference schedule. They did not do this until the NCAA teams were allowed to play 12 regular season football games.
I know that five seasons is a relatively short time frame, but during those five seasons, did the Pac-10 experience the same problems that you think the Big-10 would experience with a 9-10 game conference schedule?
I realize that there are differences between the Pac-10 during that time period and the current Big-10. However, both conferences were essentially dominated by two teams (USC and Oregon, Ohio State and Michigan).
