Shane Warne recently indicated that Fleming was the best captain in the world, to Steve Waugh's chagrin. He'll have been in the job six years but is young enough to keep going.

Under fire for saying it would be safe to play World Cup matches in strife-torn Zimbabwe, Streak may not even be in charge come February. Given the team's results, Zimbabwe captains do not tend to stay long.
