 Maybe a front comes in or it's a little bit more windy out there. You shorten up that leader. And what happens is when you shorten that leader is you keep the bait a little closer to the bottom and it doesn't rise up as far. If them fish are a little bit neutral and they're not very active, it gives them a chance at least to see the bait and you're keeping it closer to their face and it gives them an opportunity at least to bite at it.
