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.

Each year, the NHL awards the Conn Smythe Trophy to the most valuable player during the Stanley Cup playoffs. And each year since 2010, Hockey Prospectus' GVT metric has been able to accurately forecast the award winner. With the 2013 Stanley Cup finals now set, who holds the lead in the postseason MVP race?

Nearly impossible to score on in the Eastern Conference finals -- he gave up just two goals to Pittsburgh all series -- Bruins goaltender Tuukka Rask now leads the Conn Smythe watch.
