Thank God this fell through. Although it would be time to replace it by now, all cities have come to realize that the multi-purpose stadiums just give you lousy stadiums for each sport. Here in Toronto, they combined the worst of everything, the last multi-purpose stadium combined with a retractable dome that doesn't allow for real grass to be installed.
I didn't remember plans for the Wings to play in this proposal. There is no way you could re-install the ice in time with all the overlapping for baseball/football.
