I used to get my Kings news from the LA Times, The Hockey News, and the Kings Hotline which had a recording of Nick Nickson giving us weekly updates.
We've come a long way since then. I think the first actual bit of Kings news I got to follow along online was the entire Gretzky trade speculation and saga in 1995-96. Newsgroups and bulletin boards were flooded with rumors.
Nowadays, I just rely on the reputable names for Kings news. Locally, there aren't very many options, but Friedman, Dreger, LeBrun, etc. are the ones I tend to follow. Sadly, The Athletic isn't what it once was and I no longer bother with their coverage.
