Football X’s & O’s talk: any concerns with running 4-3 D with today’s modern offenses

4-2-5 baw

4-2-5 is your answer. Many formations can still be ran based off a base 4-3. In this day and age you match your defense to whatever the offense is putting out there. If they 4 or 5 wide in a spread I doubt we run a base 4-3

Mingo or Chaisson.

When you have guys like this it almost doesn’t matter what the scheme is. It’s the ole Johnny’s and Joe’s not X’s and O’s.

Admittedly I am no expert, but with offenses moving to 4/5 WRs every down, wouldn’t you prefer the 3-4 D instead? This would give you the 4th LB that can cover more effectively and rush as well - think Mingo or Chaisson.

If we are thinking about traditional 3-4 vs 4-3 the main differences is gap responsibility. The players that you need for each are fairly different (especially on the defensive line).

If it's 3-4 they play a 2 gap scheme which basically means each defensive lineman job is to control the gaps to either side if them, eat up blocks, and allow the linebackers to clean up the mess.

If it's 4-3 everyone has their own gap they must play and if one person isn't in their gap then its a big play. Defensive line is meant to be very aggressive.

Now a days you really see more of a 4-2-5 scheme out of most teams and depending in what their "base" is will depend on the types of players in those roles. Chaisson was strictly a pass rushing LB in arandas 3-4 and would be just as good of a DE in a 4-3.

The problem of last year had more to do with poor coaching and discipline. Players constantly weren't playing their gaps or got shoved out of them by the other team.

There is no such thing as a 4-3 or 3-4 anymore. no matter what they run it has to be multiple.

It not going to matter what it’s called. It will be multiple and situational as to how many linebackers and DB’s are on the field. You will likely have two tackles most of the time though and if they can pressure the middle it will make the whole defense better.

That’s why you have the 4-2-5. Nobody runs a 4-3 base defense anymore

If I’m not mistaken in his first tenure Pelini often left the third LB in against 3/4 WR sets which led to some bad mismatches.

I think you could only get away with that if your LB corps was something like Kwon/DW40/Debo

Mingo was a DE at LSU

And Chaisson was an absolute liability in coverage

Ideally, you aren’t covering a WR with a LB in a 3-4 or a 4-3. When you play 4-5 wide teams you play in a nickle or dime.
