I think I have finally figured out this guy's problem. I don't think he played much basketball in his life. He might have played some, but probably not much. He said he became a coach at 20. At 20, most ballers are playing, not coaching. He might have been balling and coaching at the same time, but I get the feeling he was coaching more than he was balling. This would explain why he has such a hard time understanding that people have/need different shots. Anyone who has played enough good basketball knows this. Then again, maybe he did play a lot of ball, and he simply doesn't get it. Who knows? I'll use myself as the example this time....
When I first started to learn to shoot, I simply copied other good shooters. I dipped the ball, 1-2 step, shot. I got pretty good at it. 90% from the FT, 80% 3PT (high school). Unfortunately, dipping the ball and 1-2 stepping was too much of a giveaway for the defense. The defense quickly learned when I wanted to shoot, and when I didn't. So, I added a stand-still shot. When they figured that out, I added a no-dip shot. When they figured that out, I added a flick shot above my head. When they figured that out, I did a power hop/jump. And it goes on. Mix these things together, and the defense has a harder time guessing the jump shot. All of this was just done by me playing pick-up ball. Imagine what professionals go through.
Pro Shot Guy has one way of thought because that is the way that works for him. It might be a good way of teaching a new player, but it is a poor way of analyzing the game. It's an awful way to make an argument. For an older guy, he hasn't figured out some of the basics yet.
