I think too many on here are reading things into other's posts that aren't there. I'll say this, and I'm done: If someone had started out cycling at 12, worked hard, got good training and coaching, trained daily, and utilized the best training, eating, and conditioning regimines, his chances of riding in and competing for the Tour de France at the age of 28 are significantly better than the same person --who takes up basketball at the same age, but only grows to 5'10", with the same exact training regimine etc. -- of playing in the NBA at the same age. (Incidentally, I know several 5'10" or less guys with better skills, including dunking and other well known basketball athletic measurements, than half the NBA, and none of them made it out of college ball).
That's how I look at or define athlete or athletic ability. If you define it differently, fine. But we will have to agree on some measure of athleticism before we can truly have a good discussion, otherwise, we will get into silly arguments about which sport is tougher. For example, the danger of cycling has nothing to do with athletic ability, at least not the kind I am talking about. If that's the case, then NASCAR drivers have to be considered at least as good athletes, and some people don't even consider them athletes at all.
See, that's the problem with this discussion. Flame away.
