I haven't followed his posts but after taking a quick look at his past posts, yes you are right. Perhaps CORFer would be a better description...
Although what interesting about TGY's posts are that during the Spurs run he positioned himself to bask in reflective glory yet preemptively provided himself with someone to blame if they lost in order to avoid the hit to his low self esteem. This way even in the event of loss he could claim victory by declaring "I told you so". Typical avoidance mechanism of someone who has experienced repeated failure in life. It's kind of sad actually.
