Togo's Gorilla :
According to the QB movement issu, i will share what i came up with after lot of testing. Your QB movement depends on
 the quality of the first pass (usually throw by the C) and on the ability of your Meat wall (OL) to block the opponent. I end
 up maxing out the Pass accuracy and the Pass distance accuracy of my first passer (C) along with
 his blocking ability.This way, my QB receive a "good first pass". So what differenciate a "good first pass" from a "bad
 first pass" ? Imo, it's a question of creating distance with the front line. I have notice that player run toward opponent
 player if he enter their "action range". That means if a QB receive a pass and he is to close of the front line, he will
 automatically run toward it and get SACKED (unless he have lot of juke stat but that is another theory ). But if the pass
 get too far from the front line, he will "lose 0.5-1 sec" just to get the ball and will probably get sacked anyway or throw a
 bad pass in precipitation. This is why your first pass have to be top class. I may be wrong on some point, but that is
 what i came up with and i hope that will help some of us.  
Thanks for taking the time to read my long and "messy" post  .
