Yes, it basically says that 65% of his starts are quality starts, and about 15% of the time he steals a game (or at least plays like he would). The chart does not have any metric about non quality starts, but logically if he has more quality starts than any other goalie, but his save% is only league average, his other starts need to be bad. Only other option would be that he faces more high danger shots than any other goalie in the league, but just from the eye test I wouldn't say that's true (also would be crazy given our D-core). Unfortunately I don't have the numbers for non-quality starts.
Crazy but not far off according to Natural Stat Trick.
Carolina was third-worst in the NHL (ahead of WAS and DET) in High Danger Goals Against / 60, 23rd in HD Chances against / 60. 2nd in the league in HD Chances For / 60, so it's a choice of aggressive playstyle that leads to those chances.
