Top 4 for me, don't know what his thought was behind putting him above Bradman.
Here's a interesting piece of note that I found regarding Trumper vs Bradman.
"Interestingly, the vast majority of cricketers blessed with the good fortune to watch both considered Trumper the more accomplished. To the best of my knowledge, 18 of Victor’s peers offered a verdict – Monty Noble, Clem Hill, Hanson Carter, Vernon Ransford, Charlie Macartney, James Kelly, Warwick Armstrong, Joe Darling, Hugh Trumble, Jack Ryder, Herbie Collins, Hunter Hendry, Arthur Mailey, Len Braund, Wilfred Rhodes, Francis Jackson, Percy Perrin and Kumar Ranjitsinhji – and of this group only one considered Don Bradman superior (Rhodes)".
