Thanks for positing this informative video. I am particularly glad to see the elbow to the defender's face call changed. Some coaches appeared to instruct their defenders to draw an offensive foul by hitting the offensive player in the elbow with their chin. No names but this seems to be similar to prostitution by paying the defender for getting too intimate with the ball handler. I have even seen cases where the defender has fallen as if shot by a rifle only to find out upon review that there was no actual contact with the offensive player's elbow.
Under the new rule, as long as the offensive player's forearms are more vertical than horizontal the foul should be called on the defensive player. This makes much more sense and will stop coaches from teaching the dangerous practice mentioned above.
