The NFL owns the stage not the voice. They undoubtedly have the power to remove the stage. The highest form of government pressuring the stage be removed is a free speech issue.
Correct. If the NFL collectively decides they support the players' on this, DJT is stepping on thin ice.
Again, how refreshing it would be to see the POTUS use his voice to unify rather than divide. He won't ask the question of "how do we solve the issue", rather he incites furor within middle class America. And, it works. He is a masterful marketer and a joke of a leader.
