To start, the Gophers are going to get paid $250,000 per game that the Vikings play in the stadium. In addition, the Gophers and the Vikings will split concession and advertising revenue, which is estimated to be about $50,000 per gameľ totaling an estimated $300,000 per game to the Gophers. Furthermore, all additional expenses during the season will be paid for by the Vikings.
One major component to this move is that TCF will need to undergo a few renovations to get the stadium NFL ready. Currently, the stadium only holds 50,805 seats, which is about 15,000 less than the Metrodome. In order to get TCF's capacity up closer to that 65,000, the Vikings will pay for new bleachers to be installed on the western end zone plaza.
Also, heating coils are to be installed under the field. Since the Gophers don't have any home games after November, there is no real need for a heated playing surface. But since the Vikings play regular season games into January, and possibly some playoff games at the end of the month, the field will need these coils.
