Surely you can simplify any sport into a similar description of your take on golf.
Golf - natural ability + technique + mentality
Football - natural ability + technique + mentality + athleticism + stamina
Tennis - natural ability + technique + mentality + athleticism + stamina
Rugby - natural ability + technique + mentality + athleticism + stamina
Athletics - natural ability + technique + mentality + athleticism + stamina
Boxing - natural ability + technique + mentality + athleticism + stamina
In my opinion any of the candidates would come from those sports plus a few more... maybe it's just me but I find it hard to accept the "greatest sportsman ever" would wear casual slacks, a polo shirt and jumper while he walks around the course.
