Middle son Nathan sent me a very interesting article on the demise of the MLB Fan Cave, the "dream summer locale" for guys who really loved baseball. It's a good read for baseball fans.
It also contains good insight into a far-reaching issue; if you measure the wrong thing, you inevitably draw the wrong conclusions.
And, if you are measuring the wrong thing, you are likely asking the wrong question to begin with.
Major League Baseball adroitly realized they were asking the wrong question and, thus, quit throwing good money after bad.
