That is irrelevant to this thread but anyway...the Hollinger stats are garbage. As far as I am aware, he gives variables whatever weights he feels are reasonable. Win shares and wins produced are statistically validated approaches - variables are given their weights in regression equations based on how accurately the weighting predicts actual wins. Basically, you start with the outcome you're interested in (that is, wins) and see how strongly each variable (e.g., scoring, scoring efficiency, rebounds, etc.) correlates with the outcome. The strength of the correlation indicates how much weight the variable should have. It's a better approach than just guessing the weight. All that said, Melo actually is having a good season and is a good player - not great but good. His FG% is down but everything else is up from his career numbers.
People always forget that stats are only good for showing what happened in the past. Way too much weight is given to predictions/projections drawn from inadequate data samples and it is the touted like its the end all be all in a discussion. I agree with you in that Hollinger's stuff is mostly garbage. He has no explanations for the constants he uses or weights given. I looked up win shares and didn't see anywhere that 3 point buckets are treated like home runs in baseball. I believe someone posted that as a reason among others to discard win shares.
I always look for stats that are essentially simple so I am still not completely sold on Win shares but the premise seems to be solid. But the important thing is to remember that past performance is only a broad indication of future possibility and Correlation does NOT equal Causation. What it does not mean is that a player with 8 years of solid performance is better in the present moment than a rookie with no past data. Though some people seem to draw such conclusions routinely.
It does have some pure entertainment value though. You posted Melo's stats for this season without even expressing an opinion, and it was immediately labelled negative bashing. Hilarious.
TKF on Melo ::....he is a punk, a jerk, a self absorbed out of shape, self aggrandizing, unprofessional, volume chucking coach killing playoff loser!!
