Yes this. I made a coach and picked the Vikings to try and build them (Niners are my fav) and even though I picked my Playbook and schemes it still shows what Viks had before... yes I can adjust player schemes, but you don't get the right players to scheme as 4-3 vs 3-4 has different schemes and different positions to select from. Example:
Niners you can scheme RE and LE and with the Viks only the LE, but you have two DT vs Niners one. Even though my made coach wants to run 3-4 and the Viks run Tampa 2.
It makes it annoying, if it is just cosmetic, but its not because I don't think it is evaluating the players completely right because you don't get the correct base positions to choose from, nor the correct types of schemes.
