Very interesting schemes...liked alot of the 3-4 T-Rex variations. good job on the others too. I played defense and coached it, so I saw where I had to flip to get the better ILB to cover deep.
Thanks BUS36, the 3-4 T-Rex is from 1990 Chiefs 3-4 and 2001 Raven's 3-4. The 3-4 Hybrid converted from 4-3 Wide Base that shifts into 3-4 Over or under at LOS! The 4-3 Wide is a formation taken directly from the Madden 2001 Ravens Playbook! Ravens used it because Ray Lewis was so dynamic!
About defensive playbooks: Some playbooks use a variety of formations to offset the offensive formations. Nickel is used when 3WR's are in etc. Other playbooks rely on subtitiution packages within the formation to match the offensive personnel! My books reflect both!
T-Rex: Formation based to match offensive personnel. Formation Includes: 3-4, 4-3, 4-2-5, 4-6, 3-3-5, Dime, Qtr.
3-4 T-Rex: Formation based to match offensive personnel. Formations Include: 3-4, 4-2-5, 4-6, 3-3-5, Dime, Qtr.
4-6 Fire: Package Based. Formations Included: 4-6.
Flexbase: Package based. Formations included: 4-3, 4-6.
I prefer package based defenses... Oh and flipping some custom plays will cause logic to be reversed! I never flip plays,shifting works better!
