you are correct pit did play some bad football that day
The Seahawks had six more first downs (20-14) and more total yards (396 to 339) than the Steelers did. Seattle won the time of possession battle by controlling the clock for more than 33 minutes. They also had one less turnover.
Worthlessbergers passer rating of 22.6 was the lowest in Super Bowl history
The Steelers scored more points. And isn't that how winners are decided? In baseball if one team has 9 hits all singles one per inning no runs scored, and another team has one hit a home run who wins. The air in Seattle must be to thin to actually understand the concept.
