Slumps are inevitable for every athlete, and those that occur at the start of the season tend to cause the greatest reactions. Tuukka Rask, last years Vezina trophy winner, currently ranks 32nd out of 40 goalies with an .899 save percentage, while last years Calder trophy winner, Nathan MacKinnon, went into Thursdays romp over the Islanders with no goals and just four assists in ten games.

Hockey analytics has started to hit the mainstream, paving the way for dozens of websites where you can find non-traditional statistics like Corsi, PDO, and player usage charts.

Players like Eric Staal become available in trade so infrequently that his steep asking price is not entirely ignorable for any team looking to make a big upgrade down the middle, such as is reportedly the case with the Toronto Maple Leafs, according to TSNs Darren Dreger. However, that is not the case with Tyler Myers, another high-priced player rumored to be available, according to TSNs Bob McKenzie.

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. These teams all have one more thing in common: None of them made the biggest overall impact this summer.

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.
