I am (just barely) too young to have watched him play first hand. My first real exposure to him was as an analyst on the CBS NBA broadcasts in the late 70's, where I thought he was outstanding. I happened to go to college with someone from Reading, MA, where a particularly shameful and vulgar racial incident happened to him and his family. He withstood, and ultimately transcended that, and many other indignities, like the warrior he was as a player. A truly great American. I almost always think it's folly to view sports as a morality play, or to view players as anything other than mercenary entertainers. But every so often, someone comes along and defies that. He is high on that list of outliers, right there with Ali, Jackie Robinson, Arthur Ashe, Billie Jean King, etc. Bravo for his stand on Chuck Cooper(which I never knew about until today), and I'm really glad to see that wrong was finally righted, and he can now fully embrace his rightful place as an HOFer.
