Yeah I struggled against the robo qb until I decided to practice my defense in practice mode. I learned all audibles,, formation changes at line, spotlight receivers, etc. I now confuse the cpu qb by showing diferent looks sometimes. For example, I love it when I have the cpu thinking I am about to blitz (show blitz) to then go into man/zone coverage when the ball is snapped. I have had intceptions and sacks this way. Its a great feeling (I even start screamin like Samuel Jackson in coach carter - "thats right, I called that muthaf***ing play!")! I really try to play the 'chess' game and try and outsmart the cpu.
No I don't stop the cpu all the time but I have had some good games trying to confuse the qb. Of course, there are sometimes when I am totally outsmarted by the offense and I get burned.
I am truly enjoying this game for what it is. I am in week 4 with my eagles franchise. I am 2-2 with no freezes yet (hopefully never) and I am playing with myskill. Never took madden iq though.
