Zone Defense Help?

[rjsuperfly66]

For some reason every time I try to play zone defense, the players have reverted back to NCAA 10 style where they lock only into their zone. For instance, I had the opponent 3rd and goal from the 11. I'm a fan of cover 2 in that situation, the receiver runs right by the safety. The safety covers him as he is the only man in his zone and then just stops, again with no other receivers running through the zone, just locking into his "zone." The receiver runs wide open through half the back of the end zone. Is there any in game adjustments that can fix this?

Zone defense awareness is flawed/broken.

I'm offline and couch games only so I'm in no way a defensive guru but something that works for me when running cover 2 is to hot route both of my outside corners to buzz zones(purple zone, right on the left stick). I find them dropping into this zone help the qb hesitate when the safety messes up. It leads to a sack or a scramble.
