Yeah okay, what was both team's conference record those two years?
If two teams have the same conference record at the top of the standings, and there isn't a conference title game, its called a shared conference title. Let me repeat for emphasis: Shared conference championship. Ohio State claims the 2005 and 2008 conference championships as we should, the BCS tiebreakers are what gave Penn State the automatic bid.
Don't be bitter because you lost to a Michigan team that lost 5 games and an Iowa team that lost four, costing you the conference championship.
