Well I don't believe that former players who get into coaching just shout "Hey, I'd like to coach!" at the wall and then get calls from NBA front offices about their coaching positions. It's my understanding that a lot of guys get a start coaching as an assistant somewhere they've come from and/or have connections, maybe they're the head coach, and they use the connection there to get some experience and get looks from colleges or higher. I guess you consider it "charity" for a guy to maybe want to coach at a small insignificant school he went to and maybe has some connection to and wants to be the one to make them succeed or put them on the map to a degree, but I wouldn't call it charity. I guess to you if someone doesn't decide to do whatever would pay the most into their pocket, they are performing an act of charity, but I think its more about personal gratification and validation, being a part of making a place you went through better.
It's completely moronic for you to on my opinions and give yours and pretend yours are fact-based, that's what makes you a giant ass. You could've responded, "I don't know I disagree, I think he'd rather play in Europe for 8 years until he's not effective and then try coaching afterwards" and opened an actual exchange, a conversation if you will... but you didn't, because you're an ass
