And on this trips play, you can see Banderas begin to cover the third guy in, but as soon as he passes him, he releases him also.

That play is ingenious, because they attack on one side, leaving two guys having to play m2m. Gerry is robber on the play,but he bites a bit on the PA fake, so that split second keeps him out of the play. And with the LB releasing to Cockrell, he's essentially out as a robber.
But you might be right. There might be certain plays where we play that type of role, but I see the m2m with LB's on the under, as well as the release to the Safeties.
I don't think this is right either. Bando is indeed in some sort of zone coverage but there is no receiver within 15 yards of him so he is basically "doing nothing." We are completely manned up on the trips with Gerry as the robber on the other side (Gerry had no chance to help on this play because he was the short route robber and they threw the deep seam route, exactly like the play above). You can tell this because the CB runs deep with the outside receiver and Williams follows the inside slot across the field on the crossing route, ending up in the same place as Gerry. If it was a zone coverage, Williams would have stayed in his quarter of the field and had help for Cockrell over the top. But because they're all in man, Cockrell has no help and is left to try to cover his man anywhere he goes on the field. Since his man is just outside the hashmarks, he can run basically any route imaginable, making that a very tough spot for Cockrell to be all by himself. I don't think the play is so ingenious as it is taking advantage of our man coverage with little pass rush and giving a pretty good quarterback time to find any of three receivers who are able to beat their man.
They aren't running a true zone though. It's a pattern match under with the LB's until they release to the safeties. At which point, it becomes m2m. Which is why Williams follows his guy after Bando releases him to Williams. The Trips was a bad example, because there are different ways to cover trips in quarters. In this case it looks like a M technique in a nickel personnel. Which means #1 WR and #2 WR are actually in m2m to CB and NB. The Mike then takes on the role that the usual OLB would take (which is a pattern match on any under routes), and Banderas is playing his "zone" until he releases to Williams, who then plays him m2m. It's not a "true zone" in what some might see as "man has this Quarter of the field". It's more nuanced than that in our case.
Our LB's look like they aren't doing anything sometimes, because when the route is deep enough and #3 isn't a threat to their "zone" they are pretty much doing nothing.
Like I said, trips was a bad example, I am just using these plays because at the time, I remember watching the LB's release to safety. I haven't re-watched the whole game again, so I am going off of memory.
I'm not saying you're wrong. We're actually both right, because the safeties do play m2m when LB releases. Which is why it has the m2m look. For example, if both #2's run deep posts, our guys would man up to each #2's and end up on the other side of the field.
Maybe there are plays where we man on specific plays. I know we go zone when we blitz, especially on our double A Gap Blitz (which isn't as effective as I thought it was going to be).
Listen, I'm not here to say "I know more than anyone" so I don't want this to sound like I'm saying you're wrong. I want this to be more informative than anything, and from what I see, this is what it looks like to me. Maybe I am wrong, and in that case, I am wrong, so be it. I am just merely relaying the information the info I know and applying it to what I remember what I see.
