The problem with INTs is not the overall number of INTs, that's perfectly fine. It's just that most of those INTs happen in or near the endzone.
As for the high amount of facemask penalties: I believe I figured out it has to do with the AI setting adjustments to 'aggressive' to go for the strip. This seems to lead to a ton of facemask penalties.
I could stop the slow sim, go to adjustments and re-set them to 'balanced' or 'conservative' but it's probably just a matter of time until the AI sets it back to 'aggressive'.
