That is definitely the kind of season that could break the playoff as we know it. While some details could change (no more ties, and Michigan, Penn State, and Ohio State couldn't all finish the way they did here), you could have an unbeaten team out of each side of a major conference, playing close championship games, leaving 5 unbeaten or 1-loss teams, with a lot of others close by, and an independent and FCS team also in the ranks of unbeatens. Would that ever cause confusion (worst case would be 12-1 SEC west champion, having won the SEC, and Alabama at 11-1, with a close loss to the winner--thus not playing the SEC championship game, and the winner with an early loss to some other well-regarded team); a similar thing happens in another conference regarded at the time as one of the strongest, then a couple of unbeatens in the other major conferences, ND, and and FCS all coming in undefeated. Chaos!
