The reason we’re uncertain about Rosenthal’s theory is because we lack good ways to test it. We should, of course, try to seek out those ways and actually do that. But until then, his theory is of very little utility. It doesn’t help us predict what the Dodgers will do. (And let’s face it, the rest of the season is not so long that a poor performance out of the Dodgers would do much in confirming it.) And because the theory seeks to explain previously observed behavior, it has the uncomfortable feeling of being a post hoc rationalization, rather than predicting something (as J. Wheatley-Schaller of Vegas Watch pointed out, the article would be much more compelling had it been written BEFORE the poor run of performance). So while Rosenthal is not necessarily wrong (saying again, absence of evidence is not evidence of absence), he’s not contributing a lot of substance to the discussion with his theory, either.
That’s it. Have a walk-off week!
