Editor's note: These rankings are based on player production in terms of Hockey Prospectus' GVT valuation metric. If you are unfamiliar with GVT and how it works, you can find more here.

Every Monday until the end of the season, Prospectus will provide updated Player Power Rankings for the top 10 skaters and top five goalies in the NHL based on HP's proprietary value metric, GVT, a statistic that combines player contributions in all aspects of the game, including defense and the shootout.

In the second edition of the rankings, a Sabre has soared to the top of the rankings on the strength of a big week.
