Good analogy, although not what you intended. Embargoes of North Korea haven't hurt Gerbil Boy one little bit, but the Korean people are starving. Same with the NFL; the poor guy selling hot dogs at the stadium is going broke while the players still get their $100k a game.
Maybe the hot dog guy will get a job at a restaurant where the owner is a decent American.
After all, those boycotting the NFL will spend there entertainment money elsewhere, won't they?
After awhile the players' salaries will go down too.
