Plenty of people in the stadium were already paying extra for seats ($100, 250, 500, ect) so there is no way the Gopher tickets were at the bottom or near the bottom of the Big Ten. The seats at Ohio State, Nebraska, Penn State, Michigan, Wisc. and Iowa are probably a lot more or a little more than TCF, but most of the rest are much cheaper than the current TCF tickets. (MSU might be the exception)
This increase is massive and will put TCF near the top in terms of cost to attend a game for the majority of the seats. Northwestern, Rutgers, Maryland, Indiana, Illinois and Purdue tickets can be had by turning in the back of a grocery store receipt, almost.
