Come on mate, we all know that ain't the case.
Would love to see an example of your teams AI acting the same as the cpu AI on Superstar. I can guarantee you can't show us them hitting, poke checking or stick lifting to the same extent as the cpu AI.
The difference is that there is a human controlling the whole team. The AI players have the exact same behavior, but the on-ice conditions due to human interaction are not going to allow them to play the same as if they were all AI. Humans aren't making the same decisions as AI players. Who know how to stay in position, look for open lanes and manage their energy. Humans aren't always playing with these in mind. They force passes into traffic, they try to use exploits, the play out of position and burn through energy.
