Beat article I've seen on the 4-3 under so far.
Thanks...adding these all to the 2017 Team Information thread.
Agree! A very good article that makes it clear that there are many variations not only to the general scheme but with each position and what players are used. For instance, many have been saying that an UnderTackle has to be smaller and quicker but this article makes it clear that is not uniform across all UnderTackle defenses. This is something I was hoping to read as I would like them to use our best players and develop/morph the scheme to the personnel's strengths.
It gets confusing when trying to figure out "who has to play where". This article is just one approach.
Looking at Carroll's lineups over the years makes it even more confusing. One year, he had a 320 lb man playing 5t (LDE). Last year he had a 310 lb man playing 3T (RDT).
None of these are rules.
There's one rule to the front in this scheme: Get talent, put it in a position to wreck offenses.
I've been trying to figure out where the best fit in a 4-3 is for AA and Buckner. I imagine that they will get moved around a fair bit, but I think Buckner is more likely to play a 5T most of the time. If Buckner does generally play a 5T then it seems likely that AA would play a 3T more often than not. But I think the best 3T players are quick off the snap and AA often is actually slow off the snap. As a 3T, though, if he gets the right leverage on the guard, he is often a nearly unstoppable. I'll admit, though, that interior line play is something I don't understand particularly well and I'm not nearly as familiar with the interior line play of a 4-3 rather than a 3-4, so my impressions could be complete bullocks.
I always appreciate your posts 49erphan...always humble too.
But it sounds like to me you've got it down. I think most could see a shuffling between AA & Buckner at LDE/5T and RDT/3T. AA is used to playing on the left. But he and Buckner have played every spot in a 3-4 so no big deal. Typically, that 5T is an edge setter, funnels runs inside and works in tandem with the SAM who lines up next to him to ensure no RB gets to the edge. They'll both usually try and blow up the RT and TE/FB. You might see some stunts here and there but it's mostly a vanilla spot and his job will be to muscle the RT into submission. If he adds any pass rush (and both Buckner and AA are capable of 6-8 sacks a year from there), it's a bonus. The 5T is certainly not an edge rusher but it could be ideal (like Bennett) if you can find a player who's equally effective at stuffing the run AND pass rushing but that's rare. The 5T is single blocked usually and he's usually responsible for just one gap. In fact, 3 of the 4 of the DL only have to deal with one gap and one blocker.
Next up is the 1T/NT. This guy is typically, the only one who has to be responsible for 2 gaps and 2 blockers. He's the work horse. Ironically, that's the former role of Buckner and AA in our 3-4. So right now, we have a number of players who could step in there in Mitchell, Purcell, Dial, Jones, Buckner & AA. Typically, you'll like a wide-bodied fatty there who's impossible to move hence why we went after Brandon Williams. But he doesn't have to be huge...but he absolutely needs to be able to hold the point of attack, anchor and not give leverage. His blue collar job frees up the 5T and esp. the man next to him at 3T.
3T is your interior pass rusher. I'd say he's the second most important pass rusher next to the Elephant (as this defense was originally designed). He's your Bryant Young...smaller DT but incredibly quick with an array of pass rush moves and a nack for penetration and blowing up running plays in the backfield and disrupting the QB's step-up lane. Solomon Thomas would be ideal there. Blair could find a lot of success there as well. Neither Buckner nor AA really fit that spot b/c neither are explosive off the line but are both good at collapsing their OL there. In short, they won't be blowing by OL and beating OL to the spots and being disruptive backfield forces. Instead, they'd have one gap and bull rush their OL back and disrupt that way.
Finally, you have your Elephant. This dude is typically in the 250-260 range and explosive as hell. He's your pure edge rusher. He too is single covered and he has one job --- get to that QB. He's bendy, has crazy balance, is as quick as he is fast (closing on QB's), etc. He's the Charles Haley/Aldon Smith of our defense.
We can get away with 3T for now but we badly need that Elephant if we want this defense to hum.
