Marcus Smart may shoot better this year, or not, but I'm not sure that video proves anything. In that clip, the new and improved Smart is taking shots closer to halfcourt than the three-point line, it appears. That far out, even if his "set point" is normally over his head, he will naturally drop the ball lower -- if you put him back another 20 feet, he'll probably drop it even further, to his mid chest, just to maximize the ability to get the ball all the way to the basket. And it seems a corollary of that is that he'll launch the ball at the beginning of his jump, and not as he's coming back down, again to try to get enough heft behind that long shot.
