Vaughan was a great captain at last ashes series. He was the key palyer that won the tournament with his mates.unfortunately he had resigned his captain role due lost against SF.Recently there were lot controversy with board members and players that is why keep changing the captains.I ask question my self, how did they decide captain's capability by one or two series. All the person has ups and downs. No one perfect in the world. Collection of errors called experience. I would suggest board members to retain him in test squad and further contest.
