A lot of times in the NFL the entire defense is keyed on one player regardless of formation and down/distance. Is there a way to implement this in the game and for the offense to counter by selecting one player as a decoy which means that while he draws double or shadow coverage the QB won't actually go to him unless in single coverage...i.e. get through his checkdowns quicker.

And on the same note but going the other way...instructing your offense not to throw to Revis Island.
