Im still confused on the defintion of a front

Basically there's even and odd fronts to start with...even have center uncovered, odd cover the center. There is usually a difference for the OL on blocking an odd front or an even front. As far as 52, 53, 33, 43...etc that's to I'd the players in the box and outside the box. 7 man fronts are traditionally more susceptible to the run in HS football, where 8 man fronts are ones you need to throw on. Everything else is important in its own right, but not as fundamental to offensive strategy. Hope that makes some sense.

What defensive innovations will we see in the next ten years? Probably not many — there's nothing new in football. But there'll be adjustments, tweaks, and without a doubt, cool new nicknames for the same idea. What is the best defense to use this season? Whatever you know best, or whatever fits your personnel best. Depends on who you are, how you operate, and what you believe.



46 Defense vs I Formation5. 46 Bear Defense



I'm no expert on the true 46 Defense. I know enough to know that it is not a 4-6 Defense (46 was the number of Doug Plank — I had to double check that with the 46 Bear Wikipedia Article). What I consider to be a bear front is anything with two 3-Technique Defensive Tackles, and a head up Nose Guard. At least, that is the simplest way to identify the front.



The Bear Defense relies on Man Coverage most of the time. It is a great run-stopping front, there's no question. But if you're not a big time Man Cover guy, you may not be excited about running it against a passing team. The true Buddy Ryan-created Bear Front also does some funky things with the backers and Strong Safety that I'm not going to get into. A great resource is Rex Ryan's book, Coaching Football's 46 Defense. Go ahead, click on it... buy it, I need the 40 cent sales commission.



With a version of this still being run in the NFL (Rex Ryan with the Jets), and a huge number of teams having it as a change-up front, I would put this as the 5th most effective defense around.





4. 3-4 Defense





Slanting 3-4 Defense No question that this is a great defense. But I don't see much of it. The 3-4 Defense is a version of the old 5-2 Defense, but there are enough significant differences to make it a separate defense. The defense is centered around 3 down linemen — normally a head up Nose Guard and two head up Defensive Ends over top of the Tackles (4-tech).



It also features two middle backers, lined up somewhere in the neighborhood of 5 yards off the ball, over the Guards. Finally, the front features two Outside Linebackers. These guys are going to be more athletic than the old stand-up 5-2 Defensive Ends. They are the natural fit for being contain-responsible, as well as handling the flats in pass coverage.



This is a good fit for a Cover 2 defense, or a Quarters/cover 4 defense. It makes a nice match-up for today's Spread Offenses because you've got a lot of speed on the field. Whether you slant the defensive front, or two gap them all the way across, will be dependent on your experiences and the talent on your roster, of course.



Modern defenses need to get the maximum number of athletes on the field, and be completely adaptable. The 3-4 Defense fits the bill, so we'll put it at #4 best defensive scheme.



3. 4-3 Defense



Quarters Coverage Alignment The greatest defense there is, in my opinion. The 4-man front is the way to go, in my opinion. And the 4-man front of the 4-3 Over/Under Front is awesome. You really need one true Defensive Lineman, the 3-Technique strong side Tackle in the Over Front. On the weak side, you can play another DT if you've got him, or a wrestler-type kid at the 1-tech Nose, a weak shade on the Center.



The ends are aligned outside shade of the end man on the line, either an Offensive Tackle or a Tight End. They're crashing hard, spilling everything to the outside, rushing the passer, and causing havoc. These guys are linebackers, freakishly fast for the defensive line.



The other linebacker-type on the field is in the middle, at the Mike Backer. He's over top of the Nose Guard, two-gapping the weak side B-Gap and the strong side A-Gap.



The strong and weak backers are more like Strong Safeties, that hybrid position everyone loves. One is probably more of a backer than the other. They, along with the two-deep safeties, make this defense so adaptable.



Any coverage, any time. Any blitz, any time. You can do it all. Check out Installing Football's 4-3 Over Front for all about how to run it.



Yes, I love the 4-3 Defense. I understand it better than anything else and can adapt it however it needs to be adapted. It works great with any coverage, but most importantly Quarters. I still feel you can get more speed on the field in a 4-3 (or 4-2-5) than you can with a 3-man front, because of the way the Ends play.



But I put it at #3 because this isn't about me, its about football. And while there may still be more teams running the 4-3 today, there are a couple of other defenses that are gaining popularity much more quickly.









2. 3-5-3 Defense



3-3-5_Cover 3For today's Spread Offenses that are putting so many speed threats on the field, the 3-5-3 (or the 3-3-5, same thing) is a great way to answer. And whenever someone is looking for the best defense to run with their undersized defense, they seem to always turn to the 3-5-3.



Just like the 3-4 Defense, you've got a head up Nose Guard, and two guys lined up head up on the OTs, usually called Ends. The defense is also called the "Odd Stack" because of the alignment of the Linebackers — 3 of them, directly behind the Defensive Linemen, or stacked. The two outside backers, or overhangs, are going to be 3 yards deep and 3 yards outside the end man on the line of scrimmage. They're the contain guys, and responsible for the flats — the natural fit, once again.



The limitation of the 3-5-3 Defense is that it really fits with Cover 3, and running it with Cover 4 or Cover 2 is more difficult than doing it with the 3-4 Defense (or the 4-3). Don't get me wrong, it can be done and lots of folks do it, but it isn't the natural fit. The advantage is that you can bring blitzes from all over the place.



Most teams running the 3-5-3 are blitzing on every play — at least bringing one guy. Those who know what they're doing don't just blitz at random, either. They're creating fronts. With a combination of slants on the defensive line, and blitzing backers, you can create almost any of the other defensive line fronts under the sun — but do it all from the same initial alignment. The masters of the 3-5-3 are playing the ultimate head game with the offensive coordinator.



It's a great defense, and it easily adapts to the 5-3 if you play a heavy run team. I'm not a huge odd-front guy though, at the moment, so my vote for the #1 Defensive Scheme in Football today goes to...



1. 4-2-5 Defense (4-4 Defense)



4-2-5 Defense Cover 3If I had to install a defense from scratch tomorrow, train some assistants, teach the kids, and have them going in a week — this is what I'm going to run. There's nothing simpler, and nothing more effective. You've got the advantages of the 4 down linemen, with the ability to plug in those faster defensive ends mentioned in the 4-3.



The responsibilities for the backers are simpler. The overhangs (if you want to call it a 4-4, call your overhangs Linebackers instead of Safeties) have contain responsibility, and cover the flats. Plus you've got a Free Safety screaming downhill on outside runs.



The only difference between the 4-2-5 and the 4-3 Defensive Line is that the strong side Defensive End will play head up or shaded inside against a Tight End, handling the C-Gap, as opposed to crashing from the outside of the Tight End. Otherwise, you've got your athletic weak side End, crashing hard on the play.



You need one true Defensive Lineman, your strong-side 3-Technique, along with another Defensive Linemen that can also be a smaller and quicker guy, playing the weak shaded nose. The backers are aligned 5 yards off the ball, outside shade of the Guards, playing the open gap to their side. Everyone plays one gap, unlike the 4-3 Defense. That 6-man box is solid, and doesn't have to change versus any offensive formation.



The coverage in the 4-2-5 is the same as the 3-5-3. Its not impossible to run a 2-high coverage, but the natural fit is the Cover 3. The blitz possibilities aren't as varied as they are with the 3-5-3, but the presence of a consistent 4-man front lends itself to better run stopping ability.



Most teams are going to face everything from Spread Offensive attacks, to Wing-T, Double Wing, I-Formation and anything else. The 4-2-5 is easy to adapt to all of these, while that 6-man box never has to change a bit. You can use a wide variety of blitzes, as well as any coverage under the sun (though I'd still base out of Cover 3, but thats just me).

Honorable Mention:





5-2 Monster Defense — Who still runs this? I don't know. But they're out there. After all, its not that different from the 3-4, so you can adapt it. I like the "Monster" part.



Double Eagle Flex — Who runs this? I don't know that either, but when I read the book on this one (Coaching Football's Double Eagle Flex Defense), I was completely fascinated. Its got some cool stuff going on. And it also has a cool nickname, the "Desert Swarm."
