The parity of the salary-cap era makes first-round blowouts far less common than they used to be. Since the new CBA was first introduced in 2005, only nine of the 72 first-round series have ended in four-game sweeps, and there were only 16 teams that were dispatched in five. Looking ahead, are there any potentially lopsided matchups coming up this spring?

The Nashville Predators hit a speed bump several weeks ago and wisely acquired Cody Franson -- only to bury him in a depth role. A similar outcome befell deadline acquisitions Sean Bergenheim in Minnesota and Curtis Glencross in Washington. For other teams, skilled players are being pushed aside in favor of far more questionable options. To secure that last wild-card spot, or an advantageous home seed, teams need to have the right players in the right roles down the stretch. Can analytics help identify some of the more obvious errors?

The NHLs 2015 trade deadline was the year of the defenseman. While no starting goalies and few prominent forwards changed uniforms, Andrej Sekera, James Wisniewski, Keith Yandle, Braydon Coburn, Tyler Myers, Zach Bogosian, Cody Franson, Zbynek Michalek and Jeff Petry headlined a long list of top-four defenders to change zip codes during the past two weeks.

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.

To get a sense of how many points a player will score when moving from the AHL to the NHL, everyone has generally used the 0.45 rule of thumb. 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.
