I was under the impression that 100% WR1 (or whichever WR you assign to that depth) means it will throw to that position every time. Didn't Jfootball prove this true a while back? His entire offense was target 1 receiver at one depth. The QB would drop back, look at the covered receiver, look at the covered receiver, look again at the covered receiver, and then either force it to said receiver, take a sack, or throw it out of bounds. You could set the defense to cover the depth, but with a good enough QB and WR combo and an offensive line to protect, it wasn't always easy to stop. That was during version 3 (current version). Did something change?
