Much has been made over the past year about what NFL players do on the field during the national anthem.
It's interesting to take a look around NFL stadiums to see how fans react when the Star-Spangled Banner is played. Of course, in the actual seats, fans stand and remove their hats. It's a different story in the stadium's concourse even though the anthem is clearly audible.
Before Sunday night's Texans-Chiefs game, about 90 percent of the crowd in the concourse stopped what they were doing and stood at attention once they realized the anthem was being played.
