Ray pointed me to this old JDB quote.

The scrambling ability is really the QB's likelihood to leave the pocket and further to scramble instead of throw the ball away. A low scramble skill really just means more of a pocket passer. The scrambling skill is one that you may just want to turn off in your weights if you don't care about that style of quarterback. It doesn't translate to another position, so you can either value a Russell Wilson style QB or ignore that attribute altogether.
This thread:
https://mfn1.myfootballnow.com/community/1/249?page=1 Scrambling was essential in the pre-0.4.1 days because of how badly pass blocking was broken and so the QB was always moving because he was always being rushed.
Pass blocking seems to be a lot more consistent - although you still see a lot of mega sack games where you sack your opponent 15-20 times - but you can usually solve those problems with adjusting OL players and not having to always rely on your QB. This is why I've deemphasized it in my weights and try not to play OL with <70 pass blocking (unless he is a rookie with a lot of potential and I want to get play experience) and ideally not <80.
Still trying to get an answer from JDB about whether Scrambling mitigates the QB being under pressure at all, which is in my opinion, the only reason that it would be as valuable as FOV anymore.
