Freedom of speech (expression) simply means that government will not abridge free speech. Whether you agree with Kapernick or not, the NFL is not the government. It is not only about winning games either. It is a business and all the teams are businesses. Whether or not Kapernick is any good is irrelevant. A large part of the NFL fan base has voted with their wallets (eyeballs, etc.) and won't support someone who disrespects a flag and national anthem that so many heros died defending. He is a total distraction and almost guaranteed money -loser. An NFL owner would be crazy to have him on the roster.
