I agree - Hockeyfights.com is not a reliable source. It's a site run by David M Singer, and relies on user contributed content. They do not disclose where they get their information on heights and weights from or how they check their numbers for accuracy. Same with Hockeydb.com. There are basically 3 options here - official NHL player pages, NHLPA players pages, or a reliable third party source like ESPN.com, TSN.ca, Sportsnet.ca, CNNSI.com etc. etc.
