This was about the PGA Tour wanting to set its own rules. The fact that the legal world entered the sports world in this matter is the center of the issue. Not Casey Martin. Not whether or not walking between a green and a golf cart was as tiring for him as it is for anyone else to walk 18 holes without the aid of a cart. And really, not for the worries of the precedent the feared ruling would set.
Golf is a game that includes walking.
Professional golf for touring pros, who are playing golf as a career, being in good enough shape to walk 72 holes in four days can make a difference. Marco Island resident and CBS Sports golf analyst Ken Venturi is remembered for his battle with exhaustion during the 36-hole final day of the 1964 U.S. Open. The penalties of walking aren't as evident as in other sports. Golf also is a mental game, and fatigue can play a factor on that facet. Walking plays a part in that.
