Duckett with fourth keeper

Boyd Duckett is working his way to a solid bag of bass. He just put keeper number four in the livewell. This one is in the neighborhood of 2 and a quarter pounds, giving him around 9 and a half pounds.  Carl Jocumsen, fishing 25 yards away, only has one small keeper. What’s the difference? Well I have some theories, but if I told you, Duckett or Jocumsen might kill me.
