Okay it does work and I will explain in the simplest way I can on how to do this to check the CPU ratings.
1) Start a game
2) After the tip, let clock run a few seconds, PAUSE GAME.
3) Go to team select, switch teams.
4) Go to Sub Menu, these are CPU ratings.
*ONLY AFTER UNPAUSING DOES THE GAME RECOGNIZE THAT YOU SWITCHED TEAMS. VERY IMPORTANT NOT TO UNPAUSE AFTER SWITCHING TEAMS.
I will record a video today of this and post in here of how to do this.
