Ya. Also stellar has sean and mikes. I can argue that if zander/valyn/vanity/fns had six months they would be just as good or better.
First of all, Vanity and FNS are eons ahead of any other IGL in NA so don't even name them in this discussion. Secondly, V1 have a great coach in immi but coaching can only help with pre planned stuff. A coach can teach you how to execute a site but he can't teach you how to handle each and every situation that can arise in the middle of the round in a game that is soooo random it's impossible to predict.
