I'm torn on this. On the one hand I don't want to be involved in bullying a young man who already seems to have a lot on his plate.
On the other hand, in basketball you earn your nicknames and he earned the nickname, "The Timelord." The fact that it's actually being used in games after sick plays means he's reclaiming it and making it stand for something else other than his youthful transgressions which is really the best way to respond to any sort of criticism.
I mean Kobe invented the nickname "The Black Mamba" for himself and for years everyone used it mockingly just to reiterate what a personalityless lame-o he was. He just kept chugging along putting up great performances and eventually forced everyone to associate the nickname with greatness It became so ubiquitous that Celtics fans appropriated the nickname and created their own slant on it for Celtics Broadcaster Brian Scalabrine.
