Aggregate NFL ratings were up 3% this week. The attendance at games is down because some teams (49ers, for example), put a bad product on the field and who wants to pay those kind of prices to watch bad football? And some teams, like the Chargers, should have never left San Diego to move to an LA market that didn't want them.
There may be initial backlash from the most ardent of Trumpers, but it won't last. Three things will happen. 1.) There will be those death knell tea partiers who can't and won't ever acknowledge any of the Orange in Chiefs numerous blunders whom will never come back to pro football. Good riddance. 2.) There will be people whom have never been interested in pro football that tune it to see how the drama of the protests play out. 3.) Most who "boycott" will return after a short time, as most boycotts play out.
The NFL will find new fans to fill the gaps left by the small minority that does stick to their boycott and it will still continue to be the money making ratings machine it has always been.
And just a side note, last night MNF, two good teams on a big stage... sellout crowd.
