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.
Periodically throughout 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, which includes offensive, defensive and shootout components.
This week, Claude Giroux claims the top skater spot from Marian Hossa and a Western Conference goalie knocks Tim Thomas out of the No. 1 spot for netminders.
