This is the biggest problem I have. It doesn't seem to matter how highly rated my corners are, or how poorly rated the receiver is. I'll have corners with coverage ratings in the high 80's covering slot receivers and TE's and they consistently get beat on these routes. Doesn't seem to matter how much of a ratings advantage my DB has, the intended target will always be open on those routes when playing man. The only times I can make a play on the ball is when the QB waits too long to throw the ball and my defender has had a few seconds to catch back up. Wouldn't be upset if that was the case against only highly rated targets. But that is definitely not the case. Zone coverage can help to a point, but I've also noticed that playing zone leads to some easy bombs by the CPU since the corner playing the deep zone will sometimes just run ahead of the WR without making any play on the ball until it's caught. And of course playing more zone means having to watch your defenders just stand around if the QB decides to take off.
