to be fair to UC, because of renovations they didn't get to play home games in Nippert last year. ...
Well, stadium capacity certainly didn't hold them back. Paul Brown seats about 65,000. In fact, the 2010 numbers you cite above include a game against Oklahoma in Paul Brown that drew 58,253.
Wow, I guess you could argue if they were playing Big 12 schools all the time that their attendance would sky rocket
Or you could argue that, if they were in the Big 12, they should just skip the improvements to Nippert and play all the games in Paul Brown because their attendance might exceed the capacity of the upgraded Nippert anyway.
The UC powers that be don't want to play at PBS, citing the desire to be on campus. I can appreciate that, though I don't see the necessity for football. In fact I argued that being downtown for football might have been better for a gameday experience - more to do before and after. Still, Nippert is going to become a tough, and very loud place to play with the renovations.
I was at that UC vs Oklahoma game, and it was an outstanding atmosphere & game. These are interesting conversations, particularly on this board where we obsess about attendance. It does show that scheduling "big games" sells tickets.
