The mostly homer-ism on this thread is silly. Hollinger's statistics at most have the Celtics underrated by one place to a team that is at worst within the margin of error of the Celtics and nearly as hot, and people say he should be fired?
At any rate, I do think he might be weighting point differential a bit incorrectly Jeff Sag. uses a diminishing value to blow outs so the value of winning by 10 instead of 1, is not the same as 20 instead of 10 (etc) - but maybe Hollinger has it right, and that stat-wise Lebron's Cavs look better. There is still a margin of error and the season is still young - so the stats can swing back towards the C's and matchups do matter when playing, he'd be the first to say his stats are one tool for analysis, not the end all be all.
Update: clarity.
