I'll defer to those who know more if they correct me.

Cover 1 Robber plays man coverage on the outside and a single high safety. The second safety moves towards the line of scrimmage and plays a zone against short/intermediate crossing routes. A lot of times this will look like a two high safety look pre-snap and at snap they'll roll the deep safety while the second collapses.

Match 3 is a bit more complicated. With a traditional cover 3, you'd have specific zones that each player is responsible for. It's easy to teach, you know where your strengths are, you know where your gaps are, etc. The Bob Diaco of defenses. If you execute it well, it's stout, but a good offense and smart OC can pick it apart.

Match 3 starts fundamentally with that idea, but adds pattern matching. In this, the DBs have a rule set that they follow (i.e., if the receiver does X, you do Y) which tells them when to attach to a receiver or ignore them. Harder to teach, kinda high risk/high reward from a mistake perspective.

I'm sure one of the other people here can go in more deeply on exactly how the pattern matching works.
