Has the league figured out the cover 2?

I really don't understand what's so difficult about the "cover 2". It's all about mismatches as well as one on one coverage. With both Safeties helping out over the top, the obvious chink in the armor is the middle of the field. Send a back or tight end up the seam. Very few linebackers can cover for that long. It's a big play waiting to happen. It's chess, not checkers!
