I did read the whole article and it is just laughably wrong on nearly every point. I don’t mean subjective points like “x is better than y”, I mean purely objective points you can fact check, like when he says PER goes into Power Rankings (it doesn’t).
You are looking only for articles that prove your point. Google search “problems with won-loss record” or something and you’ll find plenty of articles as well.
Bottom line is in every sport, scoring margin has been shown to have more PREDICTAVE value than won-loss record, and therefore is a better measure of a team’s true talent. All Hollinger does is take scoring margin, weight home wins differently than away wins (evens out for every team who has an equal number of home vs. road games) and then weight the recent part of the schedule more heavily. It’s really not rocket science and makes logical sense when OBJECTIVELY evaluating a team’s strength.[/quote]
You are unbelievably dense sometimes. It makes NO LOGICAL SENSE and is not a good predictor of champions or rankings. First off, you’re proclivity to dehydrate basketball down to just “stats” is infuriatingly and fundamentally just off. We can argue about this fundamental issue until we’re blue in the face.
But let’s go with the pure objectivity argument. His formula still sucks. Taking scoring margin to be that heavily weighted over wins is ridiculous. This is where your completely objective model breaks down in the NBA. A team that has 60 wins is typically better than one with 50 wins (as much as scoring margin is going to predict). I don’t CARE how much of a scoring margin that other team had. Bullshit. And that really goes out the window with the playoffs start.
In 16 years the team with the BIGGEST margin has won the championship 7 times (43.75%), with an avg difference 2.4 in scoring margin between the champion and their highest ranking competitor. 43.75% accuracy is is not bad, but not adequate for predicting the NBA Champion or placement of the different teams in the ranking…
Cleveland had the best scoring margin in Hollinger’s rankings in 2009 and got their ass handed to them by Orlando.
His formula is fundamentally flawed, not that helpful and that you are arguing in its defense is just perplexing as all get out. His correlation coefficient of scoring margin to number of post season wins is .58. In math terms, this sucks ass as a predictor.
I imagine your doing this because you want to save face on this thread. I can’t come up with any other fundamentally sound reason that you would be defending this jackoff’s formula. Unreal.

Man, you are stupid (and don’t understand math whatsoever). There are a lot of things you say that are pretty dumb, but I’m going to highlight a couple and if you even attempt to defend yourself again I will probably block you. I can’t keep beating my head off a wall.

OK, it’s not meant to be a perfect champion predictor -it’s simply meant to be a more true predictor of strength of team than won-loss record. Also I’ve said many times bball is about way more than stats. However, stats can assimilate information over a much larger scale than our mind can. Obviously I would rather watch 1,000 games than use 1,000 games worth of stats - but I am never going to watch that many games in a season. I’ll take 100,000 games of stats over the few hundred I have watched in my lifetime simply because, although stats give you less information on a PER GAME basis than viewing the games do, you can assimilate hundreds of games of info instantly. It’s not “game stat vs. game viewing”, its “view as many games as possible and back that up with stats on top”. I don’t think you can make any NBA argument without BOTH stats AND viewing.

And the team with the best won-loss record is 6-16, thanks for proving my point for me.

This is such a horrid statistical argument I don’t know where to start. You are making the assumption that scoring margin and win totals are unrelated. Teams with 60 wins will virtually ALWAYS have a higher scoring margin than a team with 50 wins because scoring margin and wins ARE RELATED. Never did I say they are independent.
However, given equal strength of schedule, I’d take a 52-51 team with a scoring margin of +3 over a 51-52 team with a scoring margin of -3. And I’ll gladly give you the other.

That’s my favorite argument. It was contradicted once so it’s not true!
–Last note - Even Hollinger notes that come playoff times, individual matchups mean at least as much (sometimes moreso) than power rankings. Power Rankings give a GENERAL OVERVIEW of strength. Hell he picked the Hawks to take Orlando 7 games this year and said he wouldn’t be surprised if they won despite a huge disparity in power rankings.
If you actually read him instead of making blanket assumptions you might learn something.
