The likelihood the Trump led boycott will impact the NFL next year. This year, tickets are already sold.
This isn't about the flag. It's about people who are wiling to do whatever Trump asks them to do, blindly. Anyone whose boycotting the NFL this year, and didn't boycott the NFL last year has shown themselves as such. Anyone who didn't give up their season tickets at the beginning of this season (not after week three) has shown that they actually didn't care about the kneeling until Trump told them to care.
And likely they are just pawns in Trump's personal vendetta because he couldn't buy the Buffalo Bills.
