I don't know why they'd need to. The number Dave kicks around for WM III is clearly false based on football capacity, and that show likely had spmewhere in the mid-80k range. Do some research into it. Every source besides Dave says the fixed seat capacity of the Silverdome was 80,000. With minimal empty seats in the stands and thousands of people on the floor, there's no way there were fewer than 80k at WM 3.
