Very curious about this as well, I couldn't even play 17 after I realized it didn't matter how good your d-line was, the interior got zero push. From the game play I've seen on yourube it seems that the interior o line does not get pushed back at all, so hoping that's not the case. They really need to retool the pass rushing controls, it's a huge dynamic to football.
Also, I noticed in the game review pasta padre noted that the average time to throw for a 4 man rush was over 5 seconds, that's not sim, in the NFL you have an average of less than 3 seconds, so more than likely will have to crank up the pass rush slider as I do every year.
