@ossobuco,
With all due respect, comparing the NFL to the Porn Industry is well off the mark, in so may ways.
Even the least talented NFL player is compensated at a rate which is well in excess of the average American and, likely, 99% of all porn "actors," and "actresses."
Players in the NFL are true employees or contracted agents, there is no case of a young football player from Minnesota coming to The Big Apple and being drawn into seedy games played in a cheap hotel room; lucky to get paid in money rather than bruises.
There is no level of professional or semi-professional football that even remotely compares to the "black market" porn industry.
Football players were, it now seems, deceived by the league about the effects of multiple concussions.
There isn't a Porn Organization that could even be accused of deceiving the "players" of the risks they take.
The comparison isn't apples to oranges, it's apples to skyscrapers.
