the modes you are playing ARE arcade. Even the animations for those modes are way over the top - it's action oritentated. It's call of Duty vs ARMA... I play offline NBA 90% of the time and there is nothing like that there. So of course the modes with the fun-house mirror impossible animations is more arcade and all dunks alley oops, crazy dribbles and 3's...
If you want sim you're def playing the wrong modes.
