The 34 normal formation has 13 plays which are included in all "34" defensive playbooks. The 43 Normal has 26 plays that are all included in all the "43" defensive playbooks with the exception of the 43 heavy zone which, for some reason, has only 12 of those plays. Also, the 34 pass focused has 14 of the 26 43 normal plays. I haven't recorded which plays. The 34 pass focused is the only playbook that has both 34 and 43 normal plays. Alsooooo, all defensive sets have all 12 43 under plays.. Hope that helps.. :)
