When we won Super Bowl XL, we had the second-hardest post-season strength of victory in Super Bowl history, surpassed only by the 2004 Patriots. (The 2007 Giants have since tied us.) If the Steelers win the Super Bowl this season, then we'd have to be in the running for easiest post-season strength of victory, considering two of the teams we will have played didn't even have 10 wins in the regular season.
Just throwing this out there as something to be prepared for if we manage to win two more games. People will be ready to discount us based on the strength of our opponents. The officiating was the excuse du jour last time, and our relatively weak post-season opponents will be the excuse this time if we do it again.
