I haven't had any problems with QB acc at 3. For one RGIII is one the most innacurate starters in the NFL and two if you play with a D lineman even if you don't get to the QB it seems to make them panic knowing you're chasing them and not your CPU teammate. I only play with my MLB and in year 2 of my CFM I am 1-2 so far with all 3 games being decided by less than one score. The 3 QBs I played were Mallet (63%), Manziel (54%), and Rivers (71%).
