International Debutant
Viv Richards and Don Bradman come to mind and IIRC Richie Benaud. Any others? This list covers all the captains with more than 25 tests. Among those who never lost a series, Richards has the highest number of tests:50, a record that will be very difficult to break. Benaud has 28 tests. How many did Bradman captain? Any others on that list who never lost a series?
