I've noticed this about Boat for a while and started to watch him more closely -- very seldom or almost never have i seen him go off one foot when going for a layup. He always collects himself off of two feet and imo that really slows him down and allows a defender to catch him or block more easily. Similarly, on his jump shots he hangs in the air longer and I think that also allows defenders to get to the ball easier. If he were ever to develop a runner or a quick release he would be incredibly difficult to defend I think.
