Looking at this joke of a list, I've decided not to participate as there is no serious candidate for captaincy. Captaincy means getting a free pass for several series without ever being dropped. No one in the list has the ability to think big and captain the side, all of them would be looking towards this slot to continue playing their below average game.
To replace Sarfraz find a persistent performer first who is looking to have a near permanent place in the team and is able to execute the decisions of Arthur which is even more tough.
I'd keep Sarfraz for now and change the selection committee. Need a chief selector like Aamir Sohail who has background in finding players with a proper technique. South Africa made a 22 year old Graeme Smith captain and planned the team around him which had stalwarts like Kallis. A good technique player will automatically replace Sarfraz, captaining in 3 formats is becoming a problem for him.
