Assuming this is true...
I'm all for it, as long as Jack Trice Stadium and Hilton Coliseum don't get renamed.
Principal Field, doesn't sound too bad. Or Principal Practice Facilities.
No amount of money would make me want to change the name of the stadium or coliseum, those things are priceless imo. Of course we all know who Jack Trice is, but what about outsiders? It's an honor to have somebody as the stadium name, especially Jack who passed away. Which is a priceless honor.
But $20 million should buy almost anything else.
