Is there an equivalent of a "Moneyball" for the NHL?

My draft success ranges from 80% to 100%, and that takes into accounts late picks and the percentages stand down to 1990, and it tells you to get exceptions like Martin St. Louis, Andrei Markov and Johan Franzen, so it's not only the early picks.
What data did you use to create the model? If you used a sample of historical data to create a model that "predicts" the success of players
within that sample
, then great, you've fit some equations to a set of numbers. "Predicting" St. Louis, Markov, and Franzen is a lot easier when you've created the model on a sample that includes their numbers.
How well does the model predict results outside of the data sample that created it? Have you run any tests on that? That's the true test of the model's usefulness.

I'd be interested to know what their model is and how they use it in their decision-making process. If their model predicts offence alone, the smaller forwards will stand out as bargains, but a team of small forwards will generally be weaker defensively, as defensive ability tends to go along with size and reach.
I'd agree that size has been overrated by NHL teams in the past, but draft models that only take offensive output into consideration will overrate small players as a group at least to some degree, IMO.
