If the Dallas Cowboys were a public company, I'd buy shares in it in a heartbeat. And that's because it's run by Jerry Jones, a master marketer and an expert at making money.
But my investment in the team is not financial, it's emotional. As such, Jerry's ability at generating profits is of no interest to me. So the quality of the facilities and the size of the fan base is immaterial.
What you state is indeed factual, but all that matters to me is wins and losses. And there is too much of the latter and not enough of the former. And, sadly, it will likely remain that way until Jerry ultimately dies.
