Sir Garfield Sobers was famously called the 'Five-In-One' cricketer by Don Bradman because he was an exceptional all-rounder who could contribute in every aspect of the game - batting, bowling (both fast and spin), fielding, and captaincy. Sobers is widely regarded as one of the greatest all-rounders in cricket history. Vivian Richards, Malcolm Marshall, and Jack Hobbs were not described with this specific term by Bradman.
