If I'm not mistaken, Fox Sports had us at number 1 the week before the Giants game in 2008.
Also, I can't remember us ever being #1 in a power rankings poll by the ESPNs and PFTs of the world except for some preseason ones during the "paper champ" streak of 2004-2006. Never within season. Didn't happen in 2008, 2005, definitely not in 2003, not in 1996 because of the Packers.
I remember it because the headline was "'lina Credit" and I thought that was one of the worst headlines I'd ever seen.
