Official numbers are meaningless except compared to each other. I can tell you there were easily over 30k people in attendance, it was easily our biggest crowed since the Michigan game, and if you told me we had attendance in the stands of 33k or so, I wouldn't be surprised. Obviously it would have been much better if they were all paying customers, but it was clearly the biggest crowd we had for a decade, and would have been a good crowd even in the Edsall 1 era.
And kudos to the students and whomever in the administration got them there en masse.
