Chris Paul. He is a guy who likes the spotlight, but I can also see him as someone who would love to be able to have the anonymity of this article. I also think he is well spoken, and would be able to pen an article like this.
But what really gave it away to me is that I think he is a guy who really appreciated guys who came before him, and knows what it was like 20 years ago. He is close to Jordan, and I would imagine he has told him many stories about the "good old days".
He is a guy who appreciates passion, having a mean streak, and doing what it takes to win (whether it be flopping, taking cheap shots, or hitting clutch baskets).
He also is a young enough guy that I think he really buys into the whole "rules" of trashtalking, while I think most of the veterans in the league realize that it is what it is. You trashtalk to get in guys heads, and there are no rules when it comes to that. All the rules tell you are what is actually going to work.
The calling out KG thing is played out. By now we know that the majority of players in the league think this about him (or at least they want to say it, because they don't want people to think they are intimidated), but this article on the whole has got to be the work of the little flopper.
