I noticed cover 3 is a great set to run against the CPU...and control the flat zone defender to take away the quick stuff.
They tend to tear apart cover 2 and man to man (unless your secondary is solid).
Another good look is to run a cover 1 and control the safety that drops into the yellow zone...look to take away the TE routes over the middle.
Lastly, from a slider perspective, if you feel the CPU is a little too automatic with their passes, lower CPU WR catch to 38-45 ish.
