Ok - lets try this again - which play specifically do you want to look at the one starting at 2:08? Let's start there. Saints are in a strong side right, flanker/slot left single back set with the QB under center. Patriots are in a 3 man down DL with 8 players up. It's tough to see the line splits and alignment from this camera angle, which is why I like endzone seats. #95 is lined up wide (9 tech) and most definitely is responsible for the outside shoulder of the LT and is in a good pass rush position.
At 2:13, the New Orleans line has driven the Patriots line stronside, and the LT is engaged head to head with #95 after a step back with his left foot and step forward with his right, which automatically opens up the B gap (b/w LG and LT). the running play is clearly designed to go INSIDE the tackle. THere is a LB there to fill that gap, and if the back hits the hole, he's got to either make that LB miss, or run over him.
At 2:14, the DE has shed his block and collapsed the hole. THe RB doesn't hit the hole that was there for less than a second, and instead, gets in behind the wall of offensive line that went strong side angle with their blocks, and rides their backs and blocks forward for about 3 yards, while the DE has collapsed and gets on his back.
The DE did a good job of shedding his block and closing the hole, but the OL was strong enough, to push the patriots D back enough for the RB to gain yardage anyway.
THe play at 2:10 BTW - was a pass rush, and run D, which is what was brought up here earlier - but anyway...
It's not hard to "set and edge" when an offensive run play is designed to go between the tackles.
Let's look at this one in your clip. 1:40. Now you can see the line splits. #95 is way the out there in what many would call a 9-technique, and he's in a two point stance. No tight end that side. Flanker. He gets a double team block on the snap from the flanker and tackle. He still manages to keep outside gap leverage, through the double team and force the runner back inside. Great play by the DE.
This is 1-gap control play. He's got to maintain outside leverage, primary responsibility, if he can shed the block and make the tackle inside - great, responsibility is "setting the edge"
Now - go back to your highlight clip from espn - 2 minute mark. freeze it pre-snap 1:55.

Stephen is head to head on the center, what some would call a zero-tech. He is most definitely 2-gap control run defense in the middle of the D. When you do this, when you have a nose tackle that is capable of doing this, it gives you a ton of flexibility in what you can do on defense, but you MUST have LB"s and DB's that are going to be able to make the right choices on their gap assignments as the play unfolds. Campenni is either in a 5 or 7 tech on the tackle, can't tell from the camera angle. But it looks like a 7, which would mean that the LG is uncovered, and makes sense b/c we have two players at the second LB level, that can fill those gaps b/w Stephen and Campenni on the snap, shoud the play go between the tackles.
Ashiru is lined up on the edge of the LOS and has a TE, and a flanker opposite him on the offensive formation. Unlike the play at 1:40 of the saints/pats game, he doesn't get the doulbe team. THe flanker releases to get a block down field.
At 1:58, ashiru is engaged with his block, and the flanker has engaged his block, the back now has the ball in his hand, and is running laterally with his eyes down field, looking for the gap to hit. Ashiru has driven the TE back a step or two, the flanker is locked in this block a little bit down field with Tymeer Brown, who has gone with an inside position, and the OL has collapsed on stephen and campenni - much like the saints OL collapsed on the pats D Line in the other play. But the michigan play, was not designed to go inside, had it been, the RB would have done the same thing that the Saints RB did, and ride his blockers forward for a couple yards. This play was designed to go outside. So we've got a player that is filling in to that triangle created by the engaged blocks of the OL on our DL, their TE on our OLB and their flanker on Brown. We had a LB sitting in that triangle waiting to fill either gap that the RB would take around Ashiru's engaged block Our DB, Brown, who took the wrong angle, sheds his block, to the inside, but at the same time seals our own defender who was in place to fill the gaps, and leaves the outside edge unsealed and the RB runs around the pileup to the endzone. It's a 15 yard gain, for a TD, had it been farther out in the field, it probably goes for an 18-20 yard gain at most, b/c we had other players that had closed down, but it was short field.
Does all of that make sense? Or am I full of ?
I don't see how this is a scheme problem, we had anything Gardner might do pressured and contained on one side, and we were set up perfectly to stop the run, as long as everyone maintains their gap assignments. We had one player fail to do that, and the play goes for a big gain. THat's football. It happens.
