No. It is not that most white men are evil, racist monsters (and you have to see the irony in your statement).
It's just that a certain conception of whiteness is associated with institutional, economic, and structural violence, such as colonialism, neocolonialism, slavery, genocide, segregation, etc. I am of Euro heritage (2nd generation in the US), so I see what you're saying. But that doesn't erase the legacy of these of very problematic historical facts of how white men empirically and actually behave(d) in the world.
It is very easy to see that the OP is white because the post veils (not very well) a stereotype of black athletes.
The NFL is a mixed bag of personalities and so forth. It is hyper-patriotic to please the patriots and nationalists. It emphasizes narratives of success while overcoming great odds (rags to riches or American dream). It creates good versus evil scenarios or plot lines. It is overtly violent.
At times, I think a people from an assortment of backgrounds and beliefs question their fandom, but a huge number of people still watch because the NFL is entertainment and involves all the elements of a soap opera or dramatic film.
