I suspect Miller would have averaged 50+ with the bat quite easily had he not been a bowler, which is why I pick him.
I'd say G.Chappell, Ponting and Border can all be included in that bunch, with Neil Harvey not undeserving as well.
Hammond and Sobers the sliiiiiightest bit ahead of the rest of the pack for me. Viv not far behind them, then a cluster of the rest.
* Headley and G.Pollock are difficult to rank as test cricketers due to limited opportunities. Pollock may well have been the second best ever (B.Richards too).
As I had said earlier I thought I had included Chappell and edited him in. When I look at some one to say that he is a legitimate contender for best after Bradman, they are all batsmen you can say is the second best batsman ever or at their best was the equal to the Don, as great as Border was, and he is in my AT Australia XI, I dont think that anyone can make the argument that he was the best ever or place in in an all time xi or the second team. Ponting is closer to that list and could make it. Again:
Greg Chappell, Graeme Pollock, Wally Hammond, George Headley, Viv Richards, Brian Lara, Garry Sobers, Sachin Tendulkar, Jack Hobbs, Barry Richards
The next level would include:
Ricky Ponting, Neil Harvey, Everton Weekes, Clyde Walcott, Javed Miandad, Kumar Sagakarra, Frank Worrell, Allan Border, Jacques Kallis, Ken Barrington, Sunil Gavaskar, Len Hutton.
Would also include the likes of Rohan Kanhai, Steve Waugh, Denis Compton, Clive Lloyd, Peter May, Rahul Dravid, Bobby Simpson, Gordon Greenidge and Inzamam Ul-Haq with this group.
One feature of the top tier is that they were all match winners, attacking batsmen that could destroy an attack and often did. As I said, Ponting, Harvey, Weekes, Walcott and Gavaskar are the closest to the top tier, but just (for me) missed out as it's harder to say unequivically that they were the second best ever. Border, Kallis, Barrington and Hutton though great, were not always attacking enough and had to lower their rate of scoring to be effective or that was just their natural speed (Hutton, Kallis) and were not natural match winners.
