I'm definitely on the negative side of things right now, but this is a bit too much, the title itself yells "WRONG". So if the 2008 defense wasn't good in the playoffs then how did we beat the Chargers (who had a great offense that year) and the Ravens? With our offense?
Ben made a big play to win the SB, a play that wouldn't have mattered much if Harrison (defense) didn't get a 100 yard TD INT that prevented the Cardinals from scoring 7. The defense did ALL the heavy lifting that entire year from start to finish.
