While it goes without saying, The Don is the greatest the world will ever see, I've gone for Steve Waugh simply because of his tenacity.
He wasn't the most gifted batsmen, however the intestinal fortitude he bought to the crease was second only to that of AB.
If Mrs.Waugh had given birth to one son, with Mark's talent & Steve's tenacity & strength of character, we just may have seen another Bradman!
Although he is before my time Sir Donald Bradman is my all time favorite bats man. He scored 28067 first class game runs and played 234 first class games, my dad is an influence on me as to why i like him so much but i think he is the best bats man ever to grace the Australian team.
