This is a pretty ungenerous reading of the article. Your complaint seems to be mostly about the generalizability of the model (a legitimate complaint, as you've explained) rather than its statistical validity. It still provides some interesting insights about the performance of firms at trial. Notably, there isn't a correlation between favorable judgments in those cases which have gone to trial and traditional law firm rankings. That's surprising, even if it doesn't generalize to overall law firm "success".
