Records which might not be broken

#5 Sir Don Bradman's 99.94 average in Test matches

Sir Donald Bradman was one of the finest cricketers to have ever played the game. His stats are unbelievable. In just 62 Test matches he scored close to 7000 runs at a whooping average of 99.94. If he had scored a boundary in his last innings he would have overshot an average of 100, but he was dismissed for a duck. Among the current players, Steve Smith has the highest average (61.37) which is way too far behind from Bradman's. It is nearly impossible to break this record.
