Looking through the game log (not analyzing it, but quickly glancing at it) I see that San Antonio seems to be 100% blitz - which, when you do that in 0.4.1 - especially if those blitzes have been scouted or you are using the same blitz over and over - you're going to get these kinds of results.
Got slammed by blitz (22 sacks) with nearly full speed pass protection (some still learning but these three pretty well developed with 5+ sacks this season already (3 games in)
