Yes, I would think next year will be worse unless they come out with a policy to respect the anthem. A lot of those seats are occupied by people who already bought their tickets over the summer and can't get a refund. Next year they'll have to deeply discount them to sell them, cutting into their revenues.
If I'm not mistaken they already have a policy to respect the Flag and Anthem.
It's just that the NFL, the same bunch that got all wound up over slightly under inflated footballs but routinely ignores real abuses by it's pets, selectively enforces their own rules. More equal animals and all...
Gotta keep them gladiators on TV ala "The Running Man", donchyaknow?
Just another "ass sport" like most "ball" games. Thomas Jefferson was spot on. d;^)
