Two gap vs a one gap formation – Football 201

This is 201 because I’m not going to explain certain terms, concepts, etc that were covered in 101 articles so this can be kept shorter. At the bottom of everything, is having the right talent to fit what you want to accomplish.

Jack Del Rio couldn’t do much in his 4-3 scheme because he didn’t use them in the best way for their talent. Which leads us to Wade Phillip’s and Bill Belichick’s “new” gap defense. Which really isn’t new, because it’s about giving offenses the same old school look, but slanting a DL into the 1 gap.

Technique Numbers

Football is ALL about disguises. A 1 gap formation is dependent on this.

It can look like a traditional 34; however, often five guys are used on the line. Why? Math. Three players having to attack two gaps against five guys defending them. It’s really tough to find three players all with the same talent to truly take on double teams. So, the solution? Make a hybrid system that uses the best of the 34 (four linebackers able to wreak havoc on QB’s and RB’s), but use one (or more) to shoot the gap.

How you blitz/rush is all about the outside guys. A 7 or 9 Technique guy-Sam or “Elephant”. 

I saw this term for the best edge rusher on the team and it fits. They’re big, fast, scary, mean and don’t forget…they’ll gore you. Not sure if this is why he used elephant, but I’m saying it is :).

A 1 gap defense is about showing seven and the offense guesses where they were going because they all have dual talents. This odd man line-up leaves QB’s (and OL) guessing if they are seeing a two or one gap. The drawback is stopping the run. Often the 5 techs are very good at taking on double teams and getting to the passer, but stopping speedy backs coming up the middle, not so much.

This is where ILB’s are supposed to help out. If a team is weak there, safeties will need to creep up into the box and lower the boom.

Teams who have the 5 tech guy who can play like a Sam and be the bookend to the elephant can play 1 gap. Equaling lots of QB’s on their asses.
