CPU Qb accuracy, user O line blocking and defense awareness

The default slider settings are absolutely unplayable, and even tweaking them hasn't seemed to help for me with CPU QB accuracy. I adjusted it down to 45 and they still regularly get at least 80% accuracy, and more often around 90%. I've seen some suggest putting it at 20 or lower. These games have always needed tweaking but it seems now it's worse than ever.
