This is finally starting to make some sense although I can't figure something out. I'm running a test franchise with the Colts and I have a game upcoming against the Bears. I first created a coach profile and used my dloaded Chicago playbook. As a coach I could set formation subs, so I substituted Jeremy Langford for Ka'Deem Carey to test. When I tried to start the game it glitched like crazy with players creating a dogpile on top of the football.
Next, I retired my Bears coach profile and took over the Bears 3rd QB. This worked perfectly and I could tell a difference in the playcalling immediately. The one thing that's puzzling me is that the formation subs I created stuck! Ka'Deem Carey was in every offensive formation. And no, Landford wasn't hurt, plus Carey was listed as the 3rd overall running back.
Is there an easier way to adjust formation subs and keep the custom CPU playcalling?
