Exactly. Nyquist, Tatar, Pulks, etc are different types of prospects than someone like Larkin. Larkin already does all the little things the Red Wings like and isn't so undersized and weak.
Our slow development process isn't the ideal path, but is a consequence of our situation. That is, if we were to suddenly draft a Sidney Crosby-ready 18 year old, I highly doubt that the Wings would be like "Well, he's super good but he is going to have to go through the patented, Holland Slow Cooker Process or we just won't accept them!"
The reason that Detroit has such a long development process is tied more to the fact that until recently we have had tremendous veteran depth and hadn't needed the prospect to play immediately (till our rash of injuries last season) and more importantly, due to the ridiculously long success we've had, we haven't exactly gotten first crack at top quality prospects.
The later you pick, the more flaws a prospect is going to have. Super intelligent, 6'4, 230 pound, mature 18 year old power forwards typically don't last in the 20+ draft position. That left the Wings with guys that other teams passed on but demonstrated enough potential and key attributes for us to work on. Maybe they were undersized (Zetterberg, Datsyuk, Nyquist, Tatar, etc.). Maybe there were questions about their work ethic or maturity (Mantha, Smith) or the were under-scouted and misjudged their skill ceiling (Franzen).
Point being, there are blemishes on our prospects that we believe in a good structured, and slow development process we can smooth out the rough edges and they can grow into a more complete player.
In the case with Larkin, the kid just seems to have everything clicking for him, and vastly exceeded everyone's expectations at this point of his projected development. If he proves himself to be ready, the Wings won't hesitate to move him in the NHL.
