Professional fishermen usually don't make good guides, what they can catch, most of their clients cannot. Of course there are always exceptions. But, when they struggle, and will not look at where the majority of the fish are and what they want, it adds to the pain.
One execption to this is a man by the name of John Sappington. Top notch guy and top notch guide. He teaches his clients many other tactics than the dropshot for 14" kys. He is an great example of a professional fisherman who has firgured out the Rock to put his clients on quality fish.
