I think it's clear why he wrote the article.
It's interesting that NJ may set an all-time record. But does that mean they're the worst team in the NBA? Well, if you're trying to determine which opponent will be the easiest to beat if you could play either one tomorrow, one of Hollinger's ideas he really adheres to (as do I) is that point differential and other criteria are better indicators of future success (or failure) than actual win/loss record, because the actual record can be swayed by one or two lucky (unlucky) bounces, but point differential et al corrects for that going forward.
So that's why he wrote it, because it was a way to write that the point differential approach is a more accurate indicator of a team's goodness/badness than record, though the overall record is more easily understood/open to hyperbole.
