I have noticed a lot of casual players just pick different stock coverages and don't make any adjustments other than maybe shading down.  

We can all beat the CPU, and playing against stock coverages with no adjustments is just like playing a solo challenge.

It would be nice if there were some solo challenges where part of the objective required you to do coverage adjustments using quick adjust on defense...it would really help the average/casual player improve.

For those of you who don't use quick adjust on defense, it's basically like hot routing on offense...pretty much essential if you ever want to stop a good player.
