Ok. Full admission. You and 20hrswk work for PFF - right???
Seriously - I often look up players PFF ratings but that’s because I love stats. I prefer to use my own eyes for my primary assessment (as flawed as that might be) and PFF/ESPN stats, FFB stats/etc. as complimentary.
I've got a similar process.
I use my eyes primarily for Rams players and then refer to PFF, Next Gen, ESPN, and other analytical data. Most of the time, it's within ballpark of what I expected. Sometimes it's way off, like when they say Kyren is not good at pass pro, in which case I ignore their assessment.
For non-Rams players I use the analytical data first and then my eyes because I don't see all of them play often.
