By their actions, the Chicago Cubs unnecessarily devalued Sammy Sosa as an asset, resulting in their receiving a low return when they sold that asset. That's the conclusion of new Cubs blog The Business of Baseball: With a Focus on the Chicago Cubs (which now leads the league in longest blog name). Business of Baseball writes:

The baseball market is even less efficient than the real estate market. There are only a total of 30 buyers and sellers at any given time. So, any destruction of value is amplified in this very inefficient market. This severely hinders a team like the Cubs that very publicly and continuously destroyed the value of its asset throughout the off-season.
