If you can't understand few lines in a comment then I guess your brain doesn't understand what's going on ;)
Of course they didn't tell him when to piss and when to shit but they HAD BIG influence in his success. Also I didn't say only about 'where to play every round'. I also said he had great teamplates who could hold positions.
They had A LOT OF ROUNDS (Zonic bible) and in most of them Device had clear position - he knew what he has to do. In NIP he doesn't have such organization, he doesn't have as good IGL and coach.
Also IGL is not only for pre-round stats. Mid-round calls are even MORE important IMO, right calls = more rounds won = more kills = better rating.
