I've never put any stock in competitive sports as being fair. All fairness is an illusion. People complain about the scourge of doping, but often fail to recognize that our standards of what constitutes performance-enhancing drugs and what is okay -- say, a cup of coffee (but not two!) -- are every bit as artificial as the drugs themselves. The way I see it, all sports make about as much sense as Calvinball. I'll still watch them for the display of human talent (and because I hate the f---ing Yankees) but I don't worry about fairness.
Individual sports involving nature -- skiing, surfing, climbing, whitewater kayaking, mountain biking, etc. -- are more interesting to me because main competition is between the athlete and nature. When you win at basketball, you can't know whether it's because you got better or the competition got worse; when you get that redpoint, you know.
