x1,000,000!!!
This has been my only major beef with this game, but it's been such a big one that it's frustrated me to no end.
I have played extensively with MK's Varsity set and Matt's Heisman set and have tested specifically for this issue. Those are GREAT slider sets, but I was still seeing the LDT or NT in 3 man rush fronts whip right by OGs or Cs immediately after the snap on at least half my pass attempts. That just wasn't working for me.
I lucked out, though, and think I've found the solution. I tried SEC's AA set, and I made two small adjustments: I bumped HUM pass block up 5 and lowered CPU pass rush by 5 and it's literally perfect. The issue seems to have disappeared.
Now my interior line holds up just like it should--I can step up in the pocket to deliver the ball and I'm not getting hit at 1.5 seconds every play. Most of the sacks now actually come from the DE position. I highly encourage those who are frustrated with this issue to try this set with these adjustments.
I think INTs are too high for CPU on that set, so you may need to tone those down, but something about the balance feels perfect.
Also, I recommend the rerates by Cparrish and Yukon. I use those rosters and have fantastic games.
I'd be curious to know if this helps others. Please chime in if this set + adjustments works for you!
