During the season, these rankings -- which appear on Mondays in concert with the NHL Power 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.

Previously, this list had been the top 10 players overall. Now, it's the top 10 skaters and the top five goalies. We think this will constitute an improvement in processing the info for fans, especially since goalies and skaters do very different things in an NHL game.

Check out the full rankings below. We'll be back every Monday with new editions.
