See, you still thinking about it like madden with accuracy ratings. Instead, think of it like a 3RD person shooter. You aim you fire exactly where your mouse is. There is no accuracy rating, you are the accuracy rating. What will change with different tiers of QBs is the SPEED of the throw.
I get what your saying, but it wont be like madden vision. You can see the whole field. You just have to aim at the right spot at the right time.
I think all football games have never produced a real sim throwing game. Because of the easy press button pass mechanics, under and over throwing has never been accurately simulated. This has the chance to change that in the football gaming experience.
One thing that has bothered me in football games is that stats always evened out because of all the dropped INTs. The dropped INT rate is unrealistic not sim, you throw it to a defender in SIM football and there is a great chance its getting INT, BUT its all in YOUR AIM.
But one idea I have that I am not sure of yet, all thoughts appreciated. Again, reminding everyone the passing will be like a shooter. For lower tier generic QBs, should there be "recoil" where the ball is not always exactly thrown where you fire. But higher level QBs have zero "recoil"
