I disagree with the OP.

The only base defense we have is the 3-4.

HOW we play that changes as the game goes on/players get tired/players get injured.

We ran a lot of 4-3 some games once we started to get tore up on the ground and our down 3 change on 3rd down as well.

Romeo moves people around on defense as much as Saunders did on offense...

All teams have sub-packages...

Part of the problem is mentality that if you get blocked by one person and it is a draw that you won somehow on defender, if you take up 2 blocks hurray, but 1 blocker...noooo

The Steelers run a 1 gap system, not a 2 gap system.

Straight from the horse's mouth.

Excellent work. OP will be changed in short time.

DJ and Belchers jobs are completely different.

Notice how Belcher is cheating to one side or the other presnap? That's because he watches enough film and is coached well enough to identify keys presnap that allow him to cheat to either side to gain a step in his responsibility...which is to identify the lead blocker and blow him up allowing DJ to make the tackle.

The fact that's his job and DJ was our leading tackler and Belcher was our second is a testament to how well the two work together.

What's interesting about 2-gap is that the trend is shifting to having a nose that can play somewhat across the line. Wilfork doesn't okay 20 to 25 snaps as many nose tackles do. He is now playing almost all the defensive snaps. It adds a lot of flexibility to have a nose that can rotate into a 5-technique without taking the guy off the field. The 5-technique is still 2-gap. But you see where I'm coming from.

Hence, why they went after Poe. As I've said before,I imagine the chiefs top priority is to get him to learn one position, nose tackle, wel. But in a few months, I bet he plays across the line.

The bold part is a bit off - collapse the pocket, sometimes, but never really pass rushers. A 1 gap system relies more on the 3-4 DL applying pass rushing pressure than a 2 gap system. You'll notice sometimes that a 2 gap 3-4 will also put a DL on watch for a draw ( Dorsey often has this role for the Chiefs, hanging out by the line vs working upfield ). All depends on the system, game plan, and play call.

Bills play 4-3 but you can line a 4-3 exactly like a 3-4 and play same concept. Donkeys do that with Von Miller with a 4-3 under alignment which frees up Miller to rush the passer and puts him on the line next to a DE. Marty ran DT like that back in the hey day.

I saw that video "1 Poe, 2 Gaps".

nasty

This whole post seems pretty wrong. I could be wrong, but since the Bills were just making the switch to the 3-4 under Gaily, I doubt they are already switching back. The Broncos use a 4-3, but yes they might use Miller more like Thomas.

He's right, the Bills are switching back to the 4-3.

Sucks for the Bills. You need to make a choice and stick with it. Don't be like the Raiders and make a change every year or two continuously setting your team back.

And I had no idea Wannstedt was a Bill now.

Actually no. Their personnel is more fitted for a 4-3.

So you're saying in their attempt to switch to the 3-4, they literally didn't sign or draft a single player to make the switch? Interesting.
