I'm having great success with 335 Okie. I use it as my base. I play and the ILB and the run fits are exactly the same as the 3-4 run fits. (offensive line as keys never lie
) You will need a physical #2 SS and understand when and where to set the force or you will get gashed...just like the 3-4 defense.
I recently have been working of a few blitzes. All the ones on youtube are verses 5 man protections
. 335 Okie has a few nice zone blitzes.
Recruiting for it is exactly the same as recruiting for the 3-4. DT's and DE's with high STR and BSH ratings. LBs that can run, corners and FS that can cover and Hard Hitters for SS since they are the force. I like the slower (mid 80s spd) SS that is a hard hitter, high pursuit and high tackle rating for my hybrid.
If you are comfortable with and understand the 3-4 playbook, you will love the 335 Okie formation.
