I never understood that argument. What does gameday have to do with anything? Isn't that an issue between employers and it's employee's union?
Personally, what I saw was an issue that was being handled in the private sector by employees, employers and the customers; then the president weighed in and used his bully pulpit to coerce the employers to deny the free speech of those employees through fear of retribution. And the coercion wasn't you boycotting them. It was the NFL's legal monopoly status which affords them all sorts of tax breaks and allows for anti-competitive behavior. And this was all done so that he can release a tax reform plan, that does nothing for 99% of the population and does very little for .9% of the population, without his base recognizing it.
