I am not sure how anyone is "done" in fishing. Unless some sort of medical reason occurred I would think fishing skills would not deplete. I guess the pressure of being in a slump might force poor decisions but you would think a guy like Van Dam would be way past that.
He was impressive on the last MLF shows I watched.... that last to first deal was amazing...
Never been a real big fan of any of those guys but I do respect their skills of which I have zero...
