Not to mention how little the feature would be actually used, unless a guy is running the same blitz the hole game and you know hes doing it from the people he keeps switching to and setting it up it would be an automatic sack if say he put the linemen in a yellow zone while blitzing a Linebacker in his place making the line maybe step up trying to double the linemen and linebacker comes in :S?
But idk i think its a really good idea but would have to be revamped and looked at a lot to make work right like linemen not trying to double a guy who isent blitzing
