The cure for this problem involves flicking or waving the wrist back and forth like you are waving good-bye. Emphasis needs to be placed on the flick backwards and then just let the hand go forward. Shooting properly is no little endeavor, and every player at every level especially the pro's, need to practice at least 10-15 techniques and drills daily to improve and keep their shot consistent. Detroit even though they initially gained a big lead with good shooting, showed signs that they would fall apart in a pinch because of horrendous defense. Later in the game their defense picked up now and them, but to no avail.
Proper defense starts out with proper defensive position and eyes on the ball.
Let me explain the importance of defensive position using an analogy. If a runner started a 100 yard dash from a fully upright position you would think he was stupid or inept. He would be giving his opponents a head start. No doubt he would lose the race, because to start he would need to bend down to get a good push off. Basketball players are in a 2-5 yard dash on defense.
