Well IU just released the remaining tickets for winter break in interactive map format where you can choose your seat so the official remaining tickets for the 3 games are:
1. Nebraska has 488 seats left with blocks of tickets left in the last few rows of the corner balcony sections and scattered singles in rest of balcony
2. Wisconsin has 7 main level singles left and about 1,600 in the balcony including large blocks in every part of it
3. Illinois has 88 singles left scattered throughout the balcony so it is essentially sold out
The announced attendance is always a little lower than tickets left based on past precedent so by the time everything sells you will probably have announced attendance similar to what is left now. Nebraska will probably be somewhere in the upper 16,000 range (capacity is now 17,222 since renovations). Wisconsin will be in the the mid 15,000's and Illinois a sellout.
Again I understand the reasoning but it blows my mind that Wisconsin is by far the toughest sell of the 3 Big Ten games. Illinois being a weekend makes sense to me but I thought ticket demand for Nebraska and Wisconsin would be flipped. It brings me back to the threads original point that fans are just looking to go to a game (and the week of holiday break is more convenient a lot) and do not really pay attention to the quality of the opponent which is to bad.
