It's Friday morning so forgive me...when you say.....you....as in "Shot location - basically how far you are from the highest chance scoring areas in the slot and out between the dots. Shot distance - how far you are from the goal. Shot type - like open slapshots and wristers vs. contested backhands." Is that collective you the offensive shooter.......in relation to area, distance etc, or is that the defensive defender from those areas etc?
It's everyone on the ice, regardless of position. Similar to +\-, it's just whether you were out there or not.
So if Fiala is going down the wing and runs out of room, then flings it on net from the goal line, that's not considered a dangerous chance. If he beats his man and cuts to the slot wide open, it will be a dangerous chance and everyone on the ice will get credit for a dangerous chance for. Likewise, when the opposition does the same everyone gets credit for a dangerous chance against.
In a game there is too much variation, luck, etc. But over time it adds up. Taken with quality of competition, it's very descriptive. We all know Mikey Anderson is a solid defender. When he is on the ice, many more dangerous chances are created than allowed. That's great, but when you measure his QOC and realize he's constantly rolled out against the McJesus's of the league, it puts a number to just how effective he is.
Walker has been much better lately, but when he first returned he was just awful back there. He's a player with a low DFF% who leaks quality chances on the ice, and he was out there against 4th line competition as much as possible, he's got the lowest QOC on the team. It's not uncommon for guys returning from injury.
