I may be in the minority on this, but I think the "Throw the Ball Away" trait is more effective in limiting sacks...
For instance:
I'm pretty sure I changed Alex Smith from a "No" to a Yes" and when I played KC, he'd throw it away as he was being sacked...
Ugly animation, but cut the sacks down and helped keep his Completion % realistic, so worth the trade off, IMHO...so far!
I know I changed Brees and Big Ben from "No" to "Yes" and that might have been the case for Locker too...
Not sure about P. Manning...
But I think any decent QB throws it away rater than sticks with the play, to the extent of taking a sack...
And as far as penalties go re: sacks...
I still like IG @ 80 and RTP @ 80 as well...
SEEMS to make for better pocket presence...
