THIS!!! Makes the game feel super cheap sometimes IMO. Can get ridiculous when you play good D and not jump on all of the AI's pump fakes and step throughs, only for them to make an awkward, artificial-looking shot over 2 or 3 defenders because they were forced to shoot with time running down - somehow, it seems like the CPU already pre-ordained that the shot should go in long before the shot is taken, regardless of the circumstances surrounding the possession. Especially on HoF, sometimes your only hope is to force a turnover or to block a shot.
As for roster edits - thanks for the suggestion, I will check them out. Just saying these things should ideally be good to go straight out of the box for future iterations.
