I think the qb accuracy slider and the pass reaction + pass coverage sliders all go hand in hand. If your qb accuracy is a lot higher than the reaction and coverage, qbs are going to be unstoppable. Even with qb accuracy at 40 and the reaction at 59 and coverage at 56 the qb's well a little to superhuman. If 70 is working for you then by all means use it but I think it's a little more realistic to have qbs throw errant passes here and there. Idk what is going on but I haven't been able to get any good pressure lol. My d line isn't very good but before the patch I was getting decent pressure lol
