I doubt he'd be as vocal if he wasn't expressly instructed to be so. He hasn't earned the respect of the team on the field yet and barking instructions without having done the hard yards to me seemed very very strange. Despite that he may be that rarest of talent who utterly believes in himself and has no doubt whatsoever that his new team will march to his drumbeat, lead and they will follow. When I say his team I mean it in a possessive sense.
I'm reminded of that scene from Watchmen, Rorschach: I'm not locked in here with you, you're locked in here with me.
