usually to do is to stand out and dribble to let the clock run down and then take a contested long-range shot.
Teams who get the ball for a last shot with 10 or 15 seconds left would usually be much better off to run an offensive play or action starting with 10 or 15 seconds left than to just sit with the contested three.
This shot by Lillard will likely lead to more horrible late game decisions by many star players in the future - wasting an opportunity to get a high-percentage chance to win the game so the star can try for the most dramatic ending.
