Can anyone tell me why a play wouldnt be in my defense playbook? Im trying to add more 4-3 sets to my gameplan, but im finding some that are in other teams playbook, that are not available in mine? Thought it might be because of my D coordinators preferred set, but he a 4-3 guy. What do I need to do?

Your playbook is based off your HC ... looks like he's a 3-4 guy

Ah I see, thanks for the reply.
