But functionally you're doing the same thing. Getting a 10 yard DPI call = a 10 yard catch. In football terms, it's exactly the same thing.
The much, much weirder thing is awarding points for simply making a catch. A reception is absolutely valueless in the NFL only yards (and TDs) matter. Simply catching a ball is not a positive play, it's catching a ball for positive yardage. A reception for -4 yards is a negative play, a catch for 0 yards is a worthless play as well. The value in a catch is in the yardage (or points) it generates on the field.
How is awarding points for DPI change fantasy when PPR is even further removed from football?
