As far as I can tell, neither zone nor M2M really "work". Instead, some times the DB gets lucky and knocks the pass away from the intended receiver.
Coverage doesn't discourage a QB from throwing it to a receiver -- QBs routinely throw into double, triple, quadruple, quintuple, sextuple...undecuple coverage.
And while I know Ray throws around coverage sack, I don't think I've actually seen one. I do see a lot of flawed QB logic sacks -- QBs holding the ball until the WR they are "reading" finishes a route. The flawed part of this logic means that even if it's the second or third "read" on the play, the QB is still going to hold the ball. (So if the QB reads the short route and then "reads" the long route; he's done reading until the long route is done.)
What M2M does is that it always puts a man "near" the receiver so you have a better chance of knocking the ball away. The cover attribute determines the closeness the player is but not really the coverage.
What Zone does is put a lot of people in the passing lanes so that there are more chances to bat the ball away before it reaches the receiver. Zone has obvious flaws in that players can easily go over the top or underneath the zone. While getting burned underneath isn't a game changer, getting burned deep is.
Anyway, when I have say four hours free (October), I'll dump an extended version of these observations into an Advanced Defensive Gameplanning post. Until then, I'm still experimenting.
