Why not give Eoin Morgan a go?
Couple pages back it was mentioned that Morgan's back might not be up to snuff for test cricket and he was considering giving up the short format also.
Edit: Reading some Aus papers online
Is Ian Chappel (sp) out of his f'ing mind for suggesting Smith for captain on
https://www.smh.com.au/sport/cricket. Outside of DRS issues and occasional mistake (that he has admitted too) what does Paine need to do get respect from Aus media on his captaincy. The guy stepped into a difficult situation and has started earning Aus test team the respect. His keeping is damn good, he has led with humility and I rather see Smith concentrate on his batting.
Is the Aus public of the similar opinion that Paine needs to be replace as captain? If Aus win or keep the Ashes, would you retire if you were in Paine's shoes, considering that the last Aussie captain to win the Ashes in England was Steve Waugh back in 2001.
I would like him to continue but would understand if he walks away on a high note.
