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 during the season, Prospectus provided 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.
The 2012-13 season featured the tightest grouping of top players (from a rankings perspective) in recent memory. It was Sidney Crosby and everyone else until Game 36 of the season, when Crosby's jaw injury opened up the MVP race. The race for MVP among skaters was so tight that the league's top scorer, Martin St. Louis, does not even appear in the top 10 GVT list (he finished 13th), while Jonathan Toews, who tops our list, ranked 13th in points.
On the goaltending side, Craig Anderson was the best goaltender by a fair amount for the first five weeks of the season. However, he got injured and missed six weeks, and was ultimately good but not spectacular upon his return. Familiar faces such as Henrik Lundqvist, Tuukka Rask and Antti Niemi were among the contenders for best goaltender, but ultimately it was journeyman Sergei Bobrovsky, with only 83 games of NHL experience heading into this season, who emerged as the league's best goaltender in 2013.
