http://en.wikipedia.org/wiki/National_Hockey_League_labor_dispute_(2004) Wikipedia has an ever-growing lockout entry which has some really good information. It also sets the record straight and clears up some hazy issues. The impasse section is particularly informative, clarifying the replacements situation. If anybody can contribute anything, please do. It's a great place to centralize known information and maybe even a good starting point for research.
