To me, the difference in fishing is hard work. There's a lot of difference between golfing and fishing professionals. IMO it takes a certain amount of natural ability and years of experience and total immersion in practice to achieve the top tier of the PGA TOUR. What I mean by total immersion is a professional tour coach, personal trainer, and practice 8 hours a day (usually more). The experience gets you to the mental level you need to be at to compete on the PGA Tour. Natural Ability, Experience, and Hard Work. Some have one or two but not the other. Only the ones who possess ALL THREE succeed at that level. Made AND Born.
I was a PGA Professional at the Club Pro level. The Good Lord blessed me with a little bit of natural golf ability. I had Golf Pro friends who had more natural talent than me that I believe could have had some success on Tour if they had the time and means to hire the staff to train like the Tour guys train. The only real difference between most Club Pros and Tour Pros is mental. Most Club pros play to a scratch handicap or better. (Tiger in his prime was a +7) Tour guys hit the shot they need to hit on the 18th hole on Sunday in front of 20,000 people to win.
I may be all wet here but, I see fishing as more of a learned ability than natural talent. Mostly Made. Little Born. There's little, if any, athletic ability involved. I think in most cases you could out-work your opponents to success as a pro fisherman. I don't really have the intimate knowledge of pro fishing, so I can't really explain why KVD is so dominant right now. From what I've seen he prepares better, and works smarter than most other guys. I think he's got a better system for processing all the variables in fishing, and translates that knowledge into fish in the boat. I have a little trouble seeing the natural talent involved in fishing professionally. Is it KVD's imagination? Is it his intelligence? Is it his mental toughness? Is THAT the natural talent? I really don't know. Maybe somebody here can answer that.
