I have never trusted their grading as far as coverage goes, OL grading is suspect too I thought, dont they struggle to properly grade combo blocks and don’t allocate their “points” appropriately on a lot of plays?
oh for sure it's not a perfect system but i find that their system helps OL more than any other position because of how it values consistency and how important that is to the position
doesnt matter if you pancake guys 4 times a game if you also give up 3 pressures and a sack and miss everyone in level 2
it's a position that requires steadiness which is why I find their OL grading more useful than most other positions they grade
i still dont necessarily trust their grading but i do find it a valuable corroboration tool
