I think the days of national champions regularly going undefeated is going to end. Looking at some of the potential schedules we see for SEC and Big 10, teams in these conferences are going to have to play 5-6 top 25 during the regular season, a conference title game against another top 5-10 team and then win 2-3 playoff games. I just can't imagine a group of college kids making it through a schedule that difficult unscathed on a regular basis.
I think we're going to see a lot more one loss, or even two loss national champions going forward.
