One of my daily faves is from the Toronto Star. It's called NHL watch and has a pretty detailed summary of 'what happened the day before' on and off the ice' (daily roundup) and includes injuries, movements, benchings, pairings and even rumours. In addition there's a pretty decent (though not pro) Fantasy section as well as extensive stats, rosters, payroll and pretty much anything else you need. They also keep track of all trades in a player's history and analyse said trade. It's pretty good read over your first coffee. http://tsf.waymoresports.thestar.com...ckey/index.cgi
McKeens of course has already been mentioned and Spector (sometimes).
Does anyone remember an old site called faceoff.com that used to gather articles from several syndicated newspapers? It was really good for reading columnists - that is, until canada.com/nationalpost bought it and promptly shut it down. Bastardos.
For columnists, I usually check out the Globe and Mail sports section http://www.globesports.com/hockey (columnists listed on the right). It's often rather good - like reading Satellite Hotstove everyday.
