Didn't want to mess with the threshold for fear of having other unwanted effects. For grins I tried a couple of games where I set elusiveness to 99 and throw on run to 0 (or 1). QBs really didn't seem to move much at all, including Tyrod Taylor. I had the game set with a lower pass blocking and he and Fitzpatrick were set to paranoid, hoping the idea that the pocket was less likely to hold, that they are more concerned about the rush and they aren't good at throwing the ball on the run may mean more QB rush. Didn't happen. I then tried Brady and Tannehill as scrambling QBs, set elusiveness to 99 and set Tannehill's TOR to 99. Tannehill did scramble away from the rush a few times and also did MISS some throws on the run, and ran 2 times.
Not convincing either, but right now I am thinking I'm likely going to end up with: all QBs running attributes boosted by 10 points; all QBs including pocket passers set to scramble, and see if there is some happy setting of elusiveness, speed threshold and playbook setting to allow me to have most QBs try and sometimes avoid the rush, while others like Newton get a playbook 'advantage' of more chances for the QB to be a designed runner.
I'm hope to get one more trial in tonight or Wednesday, Rodgers vs Stafford, Boost up the running numbers, set both to Ideal/Ideal, both will be set to Scramble, both will get high elusiveness and higher TOR, Stafford will get the off the shelf R&G playbook, Rodgers will get my custom R&G playbook. Keeping the sliders at their normal levels (not reducing the speed threshold) and will see what happens. No impact on the playoffs so I can give one more try at this but it may just be what it is and something I'll have to live with.
Let me know how the threshold alteration looks; my biggest concern is too many big plays considering QBs tend to have a long time to throw. I'm liking that while I see WR outrun the DB when they get in the clear, RB and TE are getting caught from behind.
