I expect most if not all, including the coaches, to take a knee if and when they start playing. The NFL has been dead to me the moment they tolerated the first one.
It will NOT be optional.
Big money media and business has too much invested to not let this sh?t show continue. So it will go on. The owners have condoned bad criminal behavior for years till they lost some fans. Then they glossed it over to appease some. Until that happens here the show will go on BUT if enough people say enough then there will be a change. Unfortunately that is not going to happen soon IMO. Yesterday for instance I almost put on the PGA before I recalled the ceremonial George felon Er Floyd memorial tee off time. So I did not and went out and bought a book to read instead. No one was in the book store.
