As far back as I can remember, and I'm getting up there, we've collected and analyzed scoring chance data here at FlamesNation. Now that we've had time to dissect all the data we had for zone entries, we figured we might as well review what we had for scoring chances.
A note: our data has proven to be nearly identical to War On Ice's data and with the web tool we use to manually collect scoring chances being discontinued, we've decided to go with War On Ice's for this analysis. They differentiate a bit more between types of scoring chances and their data is a bit more detailed because it's not hand-collected.
