The NFL and the SB that played there that year got extremely lucky and fortunate because essentially less than a week after that SB, that entire region got covered in a huge, blinding snowstorm that wouldve made logistics for SB-related activities, events, parades and even the game's attendence is stark trouble. They were lucky and Goodell and the league knew they dodged a huge one and that realization that the next time they probably wouldn't be is why the NFL will never take that chance again. Cold weather cities like Detroit, Indianapolis, and Minneapolis work well and function accordingly despite potential logistical difficulties posed by extremely cold temperatures and blizzards and that all their NFL home teams' play in comfortable, climate-controlled domed stadiums.
