Why does Siakam start his post ups so far from the rim? He is starting 17-20 feet from the basket and facing up. Trying to beat J Hart with quickness.
He starts 8-10 feet from the basket. Stay there. Fight for position. Hold him there. Then catch the ball. Instead he just gives up on the position and moves towards the ball to make an easier catch. Thus making a harder scoring opportunity for himself.
