Did an OL exhibit poor technique/footwork/power often, but it just didn't result in a pressure?
What PFF supposedly does is assign each player a score from -2 to +2 on each play. The important thing to remember is a "0" on a play is considered an average/typical performance on a play. If you have a handful of negatively graded snaps, then you have to have a handful of snaps where you go above and beyond to average it out. If you don't have those snaps where you earn a positive grade, then your overall grade will wind up being negative even though the majority of your reps are graded as "average".
I personally had a subscription to PFF, but cancelled it after noticing some glaring issues in pressures/sacks allowed recording. I don't think it was across the board, but there definitely seemed to be a pattern in making certain OL look better than they were. IMO, there is a conflict of interest since they have started doing more draft prospect coverage and they were making certain guys look better to validate their draft rankings.
A big thing people are missing, though, is there is a very tight curve for NFL OL. The elite guys are winning 98-99% of their reps and the really bad ones are still winning over 90% of the time. That's why from an analytics side, WAR for OL is so low. If the offense runs 60 snaps, it only takes a couple of bad reps per game to drop down into the bad 90% range and you have to be basically perfect to be in the 98%+ range.
