You seem to be confused, he built a team that "backed into" the Super Bowl after losing the division... after losing Jerimichael Finley who was on pace to catch more than 60 passes and put up more than 900 yards when he was injured in week 5. After losing three LBs, our starting strong safety, oh and a guy who had back to back 1200 yard rushing seasons in the two years prior. The guy who eventually did give the team at least a credible rushing threat, James Starks, started the year on the PUP and wasn't ready to go until the playoffs. Most teams wouldnt have made a the playoffs with the sort of attrition the Packers took that year and when they did get the Super Bowl. They dominated the first half until they lost Driver Woodson and Shields to injury, until the later two went down Pit's offense was ineffective. That, Cheese, is a well built team.
Of course some of the injuries may have helped, Desmond Bishop was much more disruptive than either Nick Barnett or Brandon Chillar although both players were better in pass coverage. Morgan Burnett going down forced Capers to play a lot of single high safety, which seemed to take the defense to a new level. Burnett coming back the next season allowed Capers to go back to his preferred alignments and the defense seemed to have taken a leap backward through the first two games until Collins went down and from their the unit never recovered. That being said that team went into the season with a hell of a lot of talent. That team had so much talent that Charlie freaking Peprah was a starting safety on a unit that still managed to be the best in the league. Charles Woodson coming off a DPOY, Williams played at an All-Pro level, Sam Shields a future pro bowler was number three, and three time All Pro Nick Collins, with back to back to back selections, was at Free Safety.
