From 1 full game, I see the following causes of robo QB:
-receivers are always open. Doesn't matter how quick I get pressure, he has a dumpoff waiting. Could be pass coverage or reaction causing this.
-Never off the mark, every pass is perfectly accurate. It could 100% be a QB accuracy issue. We may need to toy with lowering it. I know that may make them less aggressive, but on default they are wildly over aggressive as it is.
-Perhaps pass rush. I felt I got good pressure, only 1 sack though. It could be a compound of all three things.
