Usually it's because they forget to bend their knees. --> in the flow of the game, their innate athleticism bends their knees to make a 3. Stand around and shoot a 3? And is all arms, no lower body. Anyway, that's usually why that happens. Watch their knees on FTs more than the ball and you'll never NOT notice when they don't bend them.DKs miss turned out to give us a 3 but I’ll never understand how some can struggle with FTs and yet be able to hit 3s all day .
