Heat Check




As a part of my daily routine, I was reading Dr. Andrew Gelman's Blog and came across an interesting post which he had been sent by Jarad Niemi. It is essentially using statistics to make a case that I have been stating for months (and had recently presented this video as evidence); that case being that Chris Bosh is incredibly overrated and should not be considered one of the "Big Three" in Miami. There's nothing I love more than when someone uses methods I enjoy to support my case.

Niemi's explanation of his graph and his methods (as posted on Gelman's blog) are below:
2010-2011 Miami Heat offensive (red), defensive (blue), and combined (black) player contribution means (dots) and 95% credible intervals (lines) where zero indicates an average NBA player. Larger positive numbers for offensive and combined are better while larger negative numbers for defense are better.

In retrospect, I [Niemi] should have plotted -1*defensive_contribution so that larger was always better. The main point with this figure is that this awesome combination of James-Wade-Bosh that was discussed immediately after the LeBron trade to the Heat has a one-of-these-things-is-not-like-the-other aspect. At least according to my analysis, Bosh is hurting his team compared to the average player (although not statistically significant) due to his terrible defensive contribution (which is statistically significant).
