I'd like to hear a bit more about Alan Davidson - I've never seen the guy bowl, but the record is outstanding. What was it that made him so effective? Swing, seam position, control? How quick did he bowl, and how did he take his wickets? Are there any left handers bowling today that could compare to him, style wise?
well... from what I have read he was only as fast as bedser/barnes/ or mcgrath in his last legs. but bobby simpson, when he selected the best postwar aussie xi (lawary/simpson/bradman/chappell/harvey/border/gilchrist/ davidson/ warne/ lillee/ thompson) had davo in the team for his accurate swing bowling and ability to bowl on and on until the skipper told him to stop. guess he was right because davidson's low average and low ER combined with a high SR show that he was a very disciplined work horse. from what i remember he had a very good record in the subcontinent as well. but for the large number of amazing cricketers australia has produced over the years, he would make it to every dream aussi xi.
Pretty much what Bagapath said here is spot on, though from what I can tell he was certainly quicker than Bedser/Barnes et al, and could be genuinely fast (if not quite Lindwall-fast) when he wanted to be. And I would say that his S/R, relative to the era in which he played, wasn't too bad at all.
He was an extraordinarily accurate bowler, as seen in his ridiculous E/R, something he developed when he was just getting into the game. As a young kid he would practice his bowling out the back of his house with the stumps set up just before a hill, so if Davo missed the stumps he's have to then chase the ball down the hill to fetch it. Safe to say that he learned the value of accuracy pretty quickly.
On top of that, as Bagapath said, he would bowl all day and there are great stories and footage of Benaud cajoling Davo into bowling one more over, and then one more, and then just one more.
It's also worth noting that his record, while already exceptional in its entirety, was truly remarkable once he'd become a fixture in the Australian side. As a reserve to Lindwall/Miller etc he took 16 wickets in his first 12 Tests at an average of 33. Once given the new ball in 1957 his remaining 32 Tests yielded 170 wickets at 19. A superb bowler, who tends to get ranked generally a level or two below what he actually deserves IMO.
