Lets use the case of Don Bradman undoubtably the greatest batsmen to grace the game but how much of that was natural talent. Can we just say that the reason he was so brilliant was because he was just born with the skill or did he develop it. It also goes into a lot of other aspects of life. Was Pele naturally gifted at football? Is Warren Buffet naturally gifted with business? But lets concentrate on cricket are the great players born or made. Personally I believe that if you're lucky enough to be young and normal you have every chance to be as good or better than Bradman if you work and work.
