Any coach or member of the offensive team, other than a runner...

So a coach, on deck batter, bat/ball shagger would all be considered "members of the offensive team".

An on deck batter is permitted to be out of the on deck circle to direct a runner attempting to score. In a sense, acting as another coach.
