I've seen pros get the shanks. You heard right, even players with model mechanics can struggle to return the center of the clubface to the back of the ball. A shank is when contact with the hosel makes the ball dart off to the right. If you ever start hitting them, try this drill. Set two balls two inches apart so one is closer to you (above, inset). Address the outside ball, then hit the inside ball (above). The outside ball can ricochet, so it's wise to have a barrier protecting the next person on the range. Manipulating your body to swing differently is asking a lot; this drill works because it takes your mind off the swing. The presence of the outside ball encourages you to deliver the club on the correct path closer to your body.
