The land that Wrigley sits on is extremely valuable. If they tear down the ballpark they could make use that land for a multitude of different initiatives to make money - housing, restaurants, hotel, etc. I'm not saying that it is likely, but to state that the value of the ballpark is high or drives the value of the franchise is wrong. It's a 100 year old landmark. Nothing more. It has falling concrete, inadequate facilities, rusting, falling apart, etc. I'm sure it is tied to the value of the franchise but there are other components that are more, or at least equally as important.
