Answer
The nickname "Jumbo" is attributed to former Indian cricketer Anil Kumble due to his towering height and robust physique. Standing at an impressive 6 feet 6 inches (1.98 meters), Kumble was one of the tallest players in the history of the sport. His towering presence on the field earned him the affectionate nickname "Jumbo," which became synonymous with his cricketing persona.
