I can speculate that him pulling back on every shot and being short on seemingly every shot he takes no matter where he is on the floor means he's on his heels and/or contorting his body backwards instead of leaning with his chest slightly over his toes I'd like to have time sometime to go back and splice together his makes from early in the year to the last 4 or 5 games' misses to confirm, but it seems like he was consistently finishing with his feet inside the 3 pt line on open looks early on and now he's taking 2 or 3 steps in the opposite direction after landing or not moving at all
