From my post "The Undefeated", (with a little proof reading added):
"We are now down, ironically, to two undefeated teams, which would be prefect for the old BCS system if they both ran the table, although I don’t think either will. We haven’t ended the regular season with four undefeated teams since 2009- but we had 5 then. Fans of the old BCS are probably rooting for there to be two unbeatens so they can ask: “What we need these two other teams for?” Fans of an eight team playoff, (like me) will be rooting for there to be enough one loss teams that the combined total of them and the undefeated teams will exceed 5. Here are the total undefeated and one loss teams, year by year for the last decade:2004 4-3, 2005 2-4, 2006 2-4, 2007 1-2, 2008 2-7, 2009 5-1, 2010 3-6, 2011 1-5, 2012 2-5 and 2013 1-9, (yes, 9). That’s an average of 2- 5. There’s been more than four every year but one and in that season, we’d have had to dip into the two loss teams to fill out a top four. And there’d be a lot more than one of them."
All but four of the teams that have been recognized as national champions by the writers, the coaches or the BCS since 1936 have won all their games or all their games but one. Three of those four had a loss and a tie so today they'd have one loss and be in it or two and likely out of it. Any national championship playoff should include all the logical contenders and all the teams, (at least from power conferences) with an undefeated or one loss record should be in the tournament. If you have to have a few teams to fill out a field of pre-determined size, OK. But the sin its to exclude someone who obviously belongs there. And, yes, the bigger the playoff, (up to a point that we haven't reached yet), the greater the number of meaningful regular season games. We presently have two undefeated teams and 16 one loss teams. That will be paired down by the now more meaningful regular season games but it won't reach four, that's for sure.
