The likelihood of TCF becoming a shared facility permanently is infinitesimal. There are too many issues that can't be ironed out. The whole point of the Vikings getting a new stadium is that Wilf can monetize EVERYTHING. With a shared TCF, the Vikings would lose out on parking revenue. Then there's the questions about what would happen with concession revenue and ad revenue. Expanding the seating helps you out, but there aren't enough premium seating options/suites. And everywhere you look there is a block M and maroon and gold. There are over 1900 Block M's in TCF...how's that going to play for the Vikes? Plus, the locker room facilities would be shared. Assuming that's not a dealbreaker, there is no way the Vikes have a locker room with a giant M in the floor and ceiling. The visitor locker rooms aren't up to NFL levels.
Most importantly, its the U's property and they don't have to share if they don't want to.
I don't care how dumb so of the MN state legislators are. This isn't something to be concerned about.
