I was at Metlife for PSU and for ND. PSU game had 61K total...probably 40K PSU to 20K SU.
The ND game had roughly 77K people in attendance. There is absolutely no way in he11 that 35K were SU fans. It was absolutely 2:1 ratio for ND. 25K SU fans max. We tailgated in Lot L 10 I believe, and basically ND fans as far as the eye could see with a few SU folks sprinkled in. Sat in 316 and were outnumbered by Irish fans at least 3:1. Looking around the stadium, you saw pockets of orange, but make no mistake about it, ND fans showed up in full force. It was anything but a "home game" for SU.
