What sport do you think requires the most skill? I gotta go with golf. If you've ever been a regular golfer you know how hard the sport is and you get an appreciation for just how damn good the pros are. Especially if you've been to a tournament in person. Hitting a golf ball is hard enough as it is. There's so many different parts to the swing and all those parts have to be perfect to make good contact with the ball. Then you factor in all the different shots the pros can hit. Their ability to work the ball in different directions, add or remove spin, the short game, putting, etc. I'd say soccer is second, but I think arguments could be made for other sports, like baseball.
