In researching, this is what I've found.

While researching numbers in owning a NFL team, I found out that many teams are now worth atleast 1000 million dollars, which is a billion. Even the Chicago Bears, bought for a hundred dollars, is worth about $1.2 Billion. Imagine, George Halas bought the Bears for 100 dollars almost 100 years ago, and they are now worth 1.2 Billion. How much money do you think the Halas family now has. For me to own a team, I'd have to be basically, filthy rich now, but I can get even more rich off of owning the team. You have to spend money to earn money, basically.
