My history could be wrong, but he and noxville really drove the whole statistical analysis of games through datdota and back end crunching. Esports has been around for a while across multiple games, but Valve opened a ton of information up to the users and someone needed to come along and utilize it.
Having said that, and if you believe it, it doesn't change the fact that he never belonged on camera or to be a 'personality' that had any business being seen or heard. Guy is completely insufferable. Stay behind the camera, do your stats thing, and you probably get invited to an event to work that aspect. He just wanted more and thought he deserved it (I don't fault him that). But it ain't gonna happen.
