I came across this because the person behind this website and list, Ben Taylor, was on the Dunc'd On podcast (very good nerdy NBA pod) recently discussing the list and its criteria.
Anyway, the top 8 will be revealed over the next few weeks, but it's an interesting list with some strong analysis in the write-ups. And it's not just based on nerdy stats as this guy does a lot of video analysis, which he shows some of in the write-ups.
The criteria of the list is really interesting as well. He articulates a point that I've tried to make before in my top 25 players of the last 25 years article and elsewhere, which is that certain players are more portable and scalable than others. What that basically means, is some great players can excel more in a wider range of scenarios, and some great players are better at elevating a good team to a championship team than others.
I think most people realize this to some extent, but it doesn't get as much attention as it should IMO.
For instance, this was why I didn't have Iverson as high as some think he should be. AI was a superstar and could therefore provide a high floor for a team during his prime, but I don't think he's an ideal guy to have if the goal is to win championships. Russ is basically a larger modern day version of AI IMO.
Anyway, I haven't read through most of the profiles yet, but I'm impressed with the work and think people who care about such things should give it a look.
