How complex is fishing?

To most people fishing is nothing more than a leisurely activity, and while every one of us who enjoy fishing would agree that one of its greatest qualities is in its recreational joys there are other things that drive some anglers. One of my biggest pet peeves, which I luckily have not been exposed to yet, is someone who thinks that professional tournament angling isn't a big deal or all that hard. I was thinking about this because one of the things I love most is the challenge of fishing, so if there's a perception that tournament angling isn't worth recognition I'd like to show some people what it is they're missing.
Take a simple look at the tournament format: you fish for 8 hours, including travel time, and try to catch the five best fish of a certain minimum length (between 12 and 15 inches, usually). Simple, right? Well, if you add to that a launch time of 7 am, a lot of people would shudder. Then think that you are competing with a field of anywhere from 30-150+ anglers who are trying to do the exact same thing as you; and you are sometimes fishing on a lake that is in excess of 10,000 acres, making both navigation and finding fish an even bigger challenge; and the weather, as we know, is constantly changing, adding another challenge to both travel and catching fish; and while much of the technology of boats and fishing gear is advanced enough to not be a worry on most days, there is always the possiblity of having a boat completely dying on you while you are miles from the launch or losing your favorite bait during prime conditions. (This last problem happened to Chad Griffen at the last regular season B.A.S.S. event on Oneida Lake, and he was still able to win.) These are not the end to the complications for a tournament angler. Water clarity, temperature, surface conditions, low light, and wind also make matters difficult. So, considering this, who is the best tournament angler? I think the answer lies in something Rick Clunn said in an interview. When asked how much a factor luck plays into tournaments, he said that the longer a tournament goes on, in terms of the number of days, the less luck plays a factor. Makes perfect sense. The best anglers adjust to the conditions, including angling pressure. So, to make the matter perhaps more general, maybe the best angler is the one who makes luck less of a factor in his or her success.
