I'm not sure how many on this board pay attention to the NBA, but we all know how great of a Coach Pop is, one of the best of all-time.
I'm on my mobile so I can't hyperlink but I have attached the link at the bottom of this post in regards to his comments/thoughts about the social injustices going on in America. Full Transcript is also on the page. If you have a few spare minutes I would highly recommend looking it over.
Pop is also an Air Force veteran.
