The column I mentioned on Thursday looks a little more silly today. Georgia and Florida join USC as one loss teams. Note that this will soon lead to a variety of columns saying that "The BCS got lucky" because all these teams lost.
No. It isn't luck. It's very rare for more than two teams from power conferences to go undefeated. It happened once since the old conference tie-ins were eliminated: in 2004 (USC, Oklahoma, Auburn). While possible, it's unlikely that more than two teams will go undefeated this year, at least more than two teams from power conferences. It's certainly premature to start complaining about it.
