But hrudey, aren't you neglecting the fact your guys played against both HCA and more effort?
I mean, I never paid attention to PP100 and as far as I know this indicator might be broken as hell and not really useful. Game ratings, for instance, for SFs who get 13.5 with 35 minutes played do kind of indicate that he's quite a solid outside defender (here I'm going off my own observations of different guys at the SF spot) Though, I do think your SG had a really horrible night and that this is something to wonder at given the guy who guarded him.
If this was a single, outlier type game, sure, it would make sense that once in a blue moon a guy could shoot less than 10% against a defender who at the very best could be maybe at the same OD level as his outside shooting. But I've run enough outside offense and seen it happen way too frequently at this point to be able to point to that. I had thought it was related to Princeton as I saw it happen a lot more there, but now that it's happening in Motion (and I've seen it happen with the SG at C patient as well), I'm out of ideas.
I don't think it's HCA/effort related, at least in terms of that. I can chalk up the fact that they pulled the game out later to that, and maybe some increase of the effectiveness of defense and rebounding.
Anyway, I think I really do need to finally go through my games and start logging the incidence of games where someone shoots insanely low like this (or the rarer and happier ones where a guy goes like 8-9 from outside when he had no business doing so).
