My son has done fencing for the past three years, and he has never been "super-coordinated". That's actually what drew him to fencing in the first place - he hated all ball-based games, because he was not highly coordinated like other boys. He tried fencing and karate, and has stuck with fencing the longest. When you think about it, a human torso is a pretty easy target to hit, so fencing is not all about coordination. It's just as much mental as physical: anticipating the other fencers movements based on their style or their body position, learning what successful fencers do to improve your fencing and learn how to counter their moves, learning ways to psych out or intimidate an opponent, etc. is all part of the mental game that makes up fencing. He's actually a really good fencer now, but he still can't play basketball to save his life! I would say he has become more coordinated, but not in a way that has improved his performance in traditional ball sports. He is wrestling now however, and the coach has commented on his power and aggression, and I'm sure this comes from fencing. He is a completely non-aggressive kid when he's not fencing or wrestling.
