And it's such a selective choice. Trump sat through flag retreat just yesterday and they're not jumping down his throat.

It's almost as if the objection has nothing to do with the flag and everything to do with the players' protest of police brutality. So to go through the checklist, riots are no good, peaceful public rallies are no good, peaceful silent protest is no good. 

The message they're sending is pretty clear. There's not one form of protest against police brutality and unaccountable murder that they'll accept because they don't think brutality and unaccountable murder should end.
