I don't think so based on what is out there in the media. The family's wealth is tied up in the team and it doesn't appear that they have leveraged that into a lot of other investments that balance the portfolio.Does the family have the kind of cash to just walk away from the racetrack purchase? They don't have many assets beyond the team itself.
My theory has been that they are all in on Arlington Heights because it would leverage the team into a massive multi-use real estate portfolio for the family.
I suppose they could try to flip the old race track land or develop it themselves or sell some to if and develop some of it...but that all seems a lot more difficult without the team to anchor the project. Banks will line up with favorable terms for a revenue generating monster like an NFL team. For a low cash flow family without track record in real estate?
