For the record, I have said a couple of times on this board that I believe the reason for Scheif's lower corsi this year is because he is dragging around Wheeler who is having one of his classic slow starts (albeit with points this year thanks to Scheif) and not because he is waiting for better opportunities.
Here is Scheifele's shot chart from the 15-16 season where he had a very good CF% and a much higher rate of individual corsi attempts. It doesn't really look all that different in terms of shot location than it does for this season that you posted above. This should further raise doubts about the "Scheifele is becoming an anti- Corsi player" narrative
