I don't see the issue with players not singing the anthem. My opinion is how they feel about the anthem is not necessarily how they feel about their country and they have the right to their opinions.No it isn’t. Like I said, there are about 5 players, if that moving their lips. Wasn’t an issue then, yet is now for some reason. People get offended over anything these days.
But players may not sing for a variety of reasons. I don't believe these players are not singing as they take issue with the anthem. As such I don't think these guys not singing is the equivalent of today's players not singing, even if I don't believe it should be an issue that offends others now.
