That's as much of a condemnation as anything. I definitely have a subjective (or a Mavs homer), but the Lakers and Celtics were bot NOT in the top 10 and they were in the Finals.

That's all he really claims. Winning marginally at home doesn't mean that you're playing the best basketball. Since winning percentage only shows us one of two eventualities - that a team won or lost - then it tells us little about HOW the team performed. His team ratings peer deeper into the equation to capture something that winning percentage cannot. This is a valuable tool in evaluating performance. To say that it is flawed is really missing the point. Then, since I'm commenting in retrospect, look at how the Mavs performed in the 2010 playoffs compared to the teams ranked ahead of them in this mid-season snapshot of Hollinger's rankings. I think you can see that his objective rankings at the time did more to tell us about the quality of the Mavs than your subjective opinion.

It did work out pretty well for him that time. Unfortunately his past rankings seem to be hidden from the public, so we can't really see how the rest of the ranks work out. Yep.

You're wrong but you don't know it -- you know it now! HAHAHAHA so instead of winning percentage, these rankings use points scored and points allowed, which are better indicators of a team's quality than wins and losses. This might not sound right at first, but studies have shown scoring margin to be a better predictor of future success than a team's win-loss record. Thus, scoring margin is a more accurate sign of a team's quality. That explains why, for instance, three seasons ago the Spurs ranked ahead of the Mavericks even though they had won nine fewer games -- San Antonio's scoring margin was superior. That ultimately proved to be prophetic, as Dallas lost in the first round of the playoffs while the Spurs won the championship.
