It didn't get to be that way in a vacuum. The answer is a LOT of people give a rat's ass.
If there were corruption in a major business in the country would you not want to know? Or would you shrug it off with a "Who gives a rats ass about corporation XYZ ......."?

The average NFL team is currently worth $1.43 billion, the highest value in the 17 years Forbes has tracked professional football team finances. The $1.43 billion average is 23% more than a year ago, the biggest year-over-year increase since 1999.
Forbes team values are enterprise values (equity plus net debt) and are calculated using multiples of revenue that reflect each teams current stadium economics (with adjustments for pending new stadiums and renovations). For teams that own their stadiums, we include the revenue the team gets from the stadium (net of applicable debt payments), but not the market value of the real estate.
The NFL is by far the most popular sport on television and media right fees underpin the leagues sweeping increase in team values. Thanks to new broadcasting deals with NBC, ESPN, CBS and Fox that begin with the 2014 season, evenly-split revenue will increase to $250 million over the next four years. In addition, the leagues one-year Thursday Night Football deal with CBS will add $275 million in revenue to the league this season. And the NFLs deal with DirecTVwhich recently began to offer streaming optionsis expected to increase substantially from its current $1 billion a year fee to the league given the importance of the NFL to the value of the satellite television provider.
