In '05 it seems like players do too many triggered animations and the controls aren't very responsive...this makes things difficult. The biggest example is on steals, a lot of times you hit steal and it goes into a essentially a 2 second cutscene of you taking the ball.
Another thing is when you are on defense and are tangled up, and you hit the jump button-it doesn't do anything. If the game doesn't want you to be able to jump up effectively at that point, hitting the button should trigger and awkward jump or a foul or something - not just paralyze your player.
