Alright, so there's two types of analytics, now.
There's the publicly available stuff, which is basically just people taking data dumps and looking for correlations by rearranging this data. You get a lot of stupidity and obviously faulty conclusions out of these analytics. For an example, read every Ryan Wilson article, ever, but even some of the smarter people have made some ridiculous pronunciations from evaluating this type of information in this way (Gabe Desjardins famously declaring that "there is no such thing as shot quality," a counter-intutive counter-factual which looked right if you did the math a certain way, but was obliterated by a study on goaltending by...I forget who...the guy used to solicit ideas on one of the forums on this site a few years ago)
...
analytics became a pointless thing for fans to discuss. What analytics are valuable are invisible to us and what analytics are available to us are not particularly useful, no matter how colorful the graphs that can be made from them are.
