Not all PGA golfers are athletes, although there are some that are athletes. It is just like not all baseball players are athletes (I've seen some pitchers unbale to adequately go through a simple obstacle course). Some may be able to perform some athletic movements, but I think an athlete has great coordination, balance, endurence, dexterity which would allow them to play almost any sport. I believe a lot of PGA golfers could not compete in other sports very well because although they have mastered and fine tuned their golf swings, they don't have the skills to excell at other sports. Of course some, like Tiger, could have probaly played any sport, but just happend to have more of an interest in golf.
