I generally have sympathy and try to understand people, who like Brown, have had to overcome a lot of things stacked against them to be successful--or to just live. But I have little to none for this situation. Having a relatively comfortable upbringing, I will never pretend to understand how the things Brown has gone through will affect him. But, many others have gone before you Antonio, with less and with more difficult issues, and they have learned how to respect people and treat people properly. That is just common decency.
I cannot see how the NFL allows this to continue. Playing for any NFL team is a privilege, not a right. Like all jobs he could have, there are expectations, including moral ones. And when those are violated, the privilege can be removed. I think it is time to remove it for Antonio. Maybe then he can get the help he needs.
