I would point out here that the disrespectful behavior exhibited by professional athletes can be seen in high school sports by players, often including coaching staffs, during the playing of the national anthem. Bad behavior begins early and, left unchallenged, only gets worse.
I saw a picture a week or so ago of youth team kneeling...9-10 year old kids with their coach...(black)...
There is your role model mode, NFL....Disgusting
