Wow. That interview was odd. There is no doubt that he had to be on something in this interview. It was almost creepy.
Stephon Marbury reminds me of Ray Charles. If you didn't know anything about Ray, you'd look at him and say, "What the heck is that guy doing? He looks rediculous with his arms folded all stiff and his ear to ear weirdo smile!" But because he was blind, he never got a chance to look in the mirror (since he was a very young kid). So he really had no idea how goofy he looked.
With Stephon Marbury, it is very similar. He seems like a very well-meaning, compassionate person, but in any interview I've seen of him, whenever a reporter even brushes up against a subject that Steph might not like, Steph just says, "I'm not answering that," and I've never seen him pressed on it. In this interview, the interviewer wants to play a fun game with him where Steph is supposed to answer quickly, Steph won't even consider it. When the interviewer says, "OK fine, in 15 seconds or less" Steph still won't even let the guy finish his sentence before he says, "No way, I'm not answering that."
It seems to me like Marbury completely shuns any and all criticism. Actually, it's not even that he shuns criticism - he shuns even the implication of criticism or the suggestion that criticism may be coming! So the guy has no mirror, no one to check him and say, "Dude, what the ef are you talking about? You sound rediculous. I literally have no idea what you are talking about."
