The problem with what your asking for is that currently there is no game way to stop a madden type nano blitz in All Pro. You can say use the protections but those are so "random" as to who your lineman will block. I would like to know every assignment if possible.
I don't want them to do what Madden does and give the defense a tool and not give the offense a counter to that tool and have one year where a specific tool from the defense totally dominates the game and then you have to wait till next year for them to come with an offensive tool to balance it out only to get another offensive tool that totally dominates the defense.
Give us "smart" Lineman abilities like say you pick a center who has the "smart" or "Blitz pickup" ability and is able to give proper blocking assignments on blitzes without me doing it manually. Or give us more refined protection strategies or better yet show us who is going to block who with a diagram similar to when you hold Left Trigger to see your play when at the line that way when we can cycle through the protections and see who is going to block who and if we like it make a hot adjustment and run the play and if we don't like it call a timeout.
That way the quick snappers can't just snap it right away especially if a blitz is coming they have to cycle through their protections to see who will block who and this at least gives the defense some time to give the offense different looks.
This alone would be a great cat and mouse game between the two players with one cycling through his/her protections to cover what you think is coming while the defender is switching up looks and showing blitzes then moving guys back, that would be hot!!
Then the nano blitz would be a welcomed addition, plus add to the fact that you can signal steal, man what a cat and mouse game the pre-snap strategies would be!! Almost like Payton Manning going up against Ray Lewis and the Ravens a few years ago in a sunday night game where they were both - calling protections, showing blitzes, audibles.... the amount of movement and talking and yelling pre-snap was so much fun to watch.
