Nobody who's literate in the use of statistics thinks that a half-dozen game sample of raw corsi is at all useful to judge a player. And unfortunately, the SBNation blogs all seem to to have a terminal case of certainty, with frequent articles that slap down a single wonky metric, and demand critical thinking about every viewpoint but their own (and I could be basing that off just a few bad ones I've read, but I do get that impression).
But if you think you can't learn anything by collecting shot data, looking at a player's game, and trying to figure out why the results are as they are, the problem is with you.
So the question is: Why are more shot attempts for, happening when Reinhart has been on the ice? You've watched the games, I'm sure you can provide some insight.
