Odds - Last 8 in recent years

[satchel27]

Might be a record or stat that is just too complicated to research or find out, but I thought I would throw it out there anyway.

Anybody know how many times the odds on favorite with 8 teams remaining has gone on to win the Super Bowl? (obviously in recent years)

2010 Saints - 99.9% sure were not
2009 Pitt?
2008 Giants - 101% sure they were not
2007 Colts?
2006 Steelers?
2005 Pats - more than likely?
2004 Pats? - pretty sure they weren't
2003 Bucs?

Just curious if maybe there is a stat/percentage out there somebody knows?
