For that kind of money, it should have happened. But it isn't as easy as it sounds. Open dates matching, finding opponents for the teams you buy off, etc.
It would have cost him much more than that. He has buildings - press center, tower - in his infield. Take them out, put in field, take field back out, put buildings back in. But he's rich and nuts (in a good way) and wanted this game. Knowing him, he would have turned a profit. Game at night, **** going on all day, 160000 in the stands. He would have sold every available inch of space for sponsors.
I'll have to look up the story I did on it.
