The NFL players will not boycott like the MLB/NHL/NBA did. There is too much money to be made. The players don't really care about "social justice" or BLM (a dubious movement in its own right with seemingly no clear goals). As soon as being vocal on these issues is no longer financially lucrative (t-shirts, advertisements, commercials, widespread media support) the players will go silent. It already happened with the NBA, they boycotted for one day, threatened to not play the rest of the playoffs, and then had a league-wide meeting where the financial repercussions were discussed and the next day they were promptly back to playing ball. It's easy to be an outspoken activist when you are still collecting your $25 million paycheck while not playing. As soon as there is the chance that is taken away (through TV networks withdrawing contracts or some other method) the players drop it and then simply pay lip service to the movement.
It's a sad fact that the issues black people face in this country are widespread and systemic. It's not something that can be solved in a week. There is no law that you can pass to "stop killing black people". It is first and foremost a matter of education and upbringing - the cycle of poverty and absentee fathers along with a certain lack of personal responsibility are the real issue. But it's much easier (and much more lucrative for the media) to point to videos of white cops shooting people who are more often than not violent criminals. It's a defeatist attitude that does no good and will solve nothing; because these cops will be arrested and white people will say "look, we arrested them! You should be happy!" and black people will respond "That isn't enough! You don't get it!".
The issues with black people start in the home, and they continue throughout school years. Sports are sadly a huge contributing factor. Just look at the anti-Semitic comments certain athletes made the past few months. Where were the protests and media outcry for those comments? Desean Jackson literally posted a quote that he thought was from Hitler. Yet Drew Brees was crucified for comments that were perhaps poorly timed but not malicious.
Comments like Jackson's stem from him being an environment where from a young age he was a star athlete and pushed through school. I've seen it happen in my own life. A kid in middle school shows a talent for sports, but struggles with school. He gets pushed through anyway, and then in high school he reads at a middle school level but his teachers help him out and make sure he gets good enough grades to stay eligible. And now he's in college and we all know star athletes aren't in college to play school. And then he hits the NFL and is immediately a millionaire, and here we are in 2020 with a 30+ year old man with what amounts to a 9th grade education spouting nonsense and receiving next to no backlash for it (invites to interview with a Holocaust survivor? Really?).
Sorry for the essay. I wanted to comment on the BLM and sports stuff but it kind of turned into a larger commentary on the issues we're dealing with today. I just think the police stuff is a scapegoat for issues that are far deeper and much more difficult to solve. These aren't issues where you can pass a law and everything's fixed. They're problems that will take generations to fix. You can't legislate changes to culture.
