+1 here... I've toyed with blitzing a LOT in test games in varied configurations and pretty much have come to the same conclusion. In fact, the more I blitz, the closer the score is and the less sacks I get. I've had my settings at 0% blitz for the entire season in actual games, yet I lead D-II Romero in sacks with 86. Seems that 0% blitz would certainly still get sack numbers in the form of coverage sacks, but shouldn't lead the next closest team by 11.
