I don’t understand how these grades work. Conner had 13 tackles officially and a pass break up against Pitt and is ranked 5th in the nation in Run stop percentage. But grades poorly? I must be missing something. Anyone help me out?
Here's an article about how they grade defense:
https://www.pff.com/news/pro-how-pff-grades-run-defense The article didn't give a specific grade for Conner. I would presume he graded 100 on the 13 tackles and the pass breakup, but there were presumably other plays where he got blocked, or failed to complete a tackle, and thus was downgraded by PFF. In any case, the grade, and specific things to work on, that he got from his coach is far more important than this grade. This grade is just a novelty, a piece of interesting information, that may give fans another perspective.
