ok i want to set up an aggressive defence, i want to destroy the enemy QB sacking him, hunting him without pity...

so i will play with 2 Def Ends and 2 OLBs, and i will keep a SS and a FS in the center.
now, i ask u, it is too much aggressive ?
another question, why dont u set up the option to do Blitzs with the Defence ?

DEs will always get preference for sack calculations, so if you're looking to put some decent talent for getting sacks put them at DE

there's no probs putting in both DEs and OLBs, the standard 4-3 that a lot of people play here is;
OLB -- MLB -- OLB
DE - DT - DT - DE

however in this lineup, it will nearly always be your DEs getting the bulk of your sacks

@stoo

about the formation i have in mind this one, but i dont really know if it has sense ( u know i'm italian i'm more skilled if we speak of 4-4-2 etc lol )

CB-------END-T-NT-T-END--------CB
OLB-----------OLB
---------------SS----------------
---------------FS----------------

also, i for the offence i want to do some lols with an OLine very very long with a couple of TEs
like this

WR---------TE-T-G-C-G-T-TE
------------------QB------
---------------------FB---
------------------HB------

we are into the limit of decence or it would be better i go back to do soccer menagerial games ?

In G-I only th DEs and both MLBs and OLBs get sacks and pressures. So if you are looking for sacks, it be best to run a 4-3 or 3-4 defence.

DE-DT-DT-DT
OLB-MLB-OLD

DE-NT-DE
OLB-MLB-MLB-OLB

If you are in lower divisions, the 3-4 will however suffer against the run using this defence. Also there is 1 less DLmen of it may work against the DL having more double teams from the OLmen.

I suggest a 5-3 for younger teams. I know some of you probaby think Im crazy but, it's great against the run and if someone does pass a little you can put your strongest guys at CB's and safety so the chance of missing tackles is less.
