How many times has a 19-year old who was winning every major in the game suffered a career-ending injury due to a horse riding accident?
Accident. Relevant word here. The stabbing was a premeditated attack.
How many times has a man who had won a CYGS (and 9 consecutive major tournaments) been denied the chance to play six years of his career due to a World War?
Laver missing all major play '63-'67, is often not spoken off too.
