Aus & WI own it to a ridiculous extent. Either side on their own would be a tough ask for a World XI to take on.
More interesting.
Oceania:
Trumper, Turner, Bradman, Chappell, Border, Gilchrist, Miller, Hadlee, Warne, O' Reilly, Lillee, 12th man Waugh
Asia:
Gavaskar, Hanif Mohammad, Dravid, Tendulkar, Miandad, Sangakkara, Imran Khan, Kapil Dev, Wasim Akram, Waqar Younis, Muralitharan, 12th man Jayasuriya
Africa:
Richards, Smith, Kallis, Pollock, Nourse, Flower, Proctor, Pollock, Pollock, Tayfield, Donald, 12th man Faulkner
England and WI teams as they are, though a WI outfit much tougher to pick. Real source of discussion is the Asian team.
Bagapath - I'd have G. Pollock over Crowe in your RoW XI, batting at five, Hammond at three.
