Or we could chose more relevantly choose the dates of Warne's career - 1992 to 2007.
Australia has the least, but by less than I'd have thought - a slight misconception caused probably by the length of time Border had been in office already by that point (if we widened the dates out from the time Border took up the role until today for instance, the difference becomes more stark), and by the fact that Taylor's prolonged slump aside, none of the captain's have ever looked insecure in their position aside from the few months ahead of their retirement, and that even in those times, there's been a clear succession plan. The four captains were in place uninterrupted, whereas in several of the other nations, it went back and forth a couple of times between some of the captains.
