If you want your players running a tighter pass coverage you need to increase the
User Pass Coverage and
User Pass Defense Reaction Time but since both of those are at 100 it seems that your corners are getting beat more often than not; try playing zone defense or run a press man coverage and try to get any pass rushers to the QB..
If that isn't helping any, you can always lower the
CPU WR Catching a few points (
at most I would lower it by 5 - 7 points) and lower the
CPU QB Accuracy by (
at most) 5. That should make it so that the CPU has a more difficult time getting the ball to the receivers; and they don't make those miraculous grabs.
