oh the color are the zones to which the defensive players are going to go when the ball is snapped.
If he is rolling out all the time you will want to put your defensive ends on contain. To do this you must click
then down on the
(this is for playstation, do the same if you are on 360) so when the qb rolls out the defender will be right there.
If he is throwing it deep to one player mostly, you can always highlight that specific wr. To do this you press and hold
then click the icon to which receiver he throws it to. You will notice that there will be a circle underneath that player.
You can always play as the safety and run with the wr if that doesn't work.
