So you want a stat that shows not only the amount of shots but also their difficulty. If only we’ve had one!The whole point is that stats don't provide the wider picture. That's common knowledge. Stats will show he's saved x amount of long shots, you'll say he's great at them then. Yet in reality he's barely had one to save that's actually challenged him.
I'm sure you'll have a +/- xSgNa stat to 'prove' otherwise but they clearly don't take wider context in to account either.
Which context aren’t they taking in account exactly?
