Solid blue-line options can be very difficult to acquire, making the potential availability of Arizonas Zbynek Michalek, Edmontons Jeff Petry and Carolinas Andrej Sekera too tempting a set of targets to wait until the March 2 NHL trade deadline. Similarly, the early drop-off of these three teams could mean that Carolinas Eric Staal and Alexander Semin arent the only significant forwards who could get snatched up by the early birds.

When the Los Angeles Kings hoisted the Stanley Cup this past June, they stood not only as the leagues champions but also as the best possession team in the NHL for the previous three seasons combined -- and by quite a margin.

A great use of statistical hockey analysis is to find underrated players, like Colorados Ryan OReilly. While a certain portion of his undeniable talent can obviously be picked up by simply watching him play, the full extent of his highly-disciplined defensive talent and possession-driving playmaking abilities can be more fully grasped when studying the underlying numbers.

It's been a busy summer for many teams. The Philadelphia Flyers underwent a major overhaul, shipping off Jeff Carter and Mike Richards to make room for Ilya Bryzgalov and Jaromir Jagr. The Minnesota Wild and San Jose Sharks traded stars -- Martin Havlat for Dany Heatley -- and the New York Rangers won the Brad Richards sweepstakes.

Multiply their AHL scoring by that magic number and you can get a fairly accurate picture of how they will do in the NHL. Lately, we have been taking a deeper look at AHL-to-NHL translations, and seeing if we can improve on this simplistic approach.
