Given the remarkable strength of the Australian lower order at the moment, I thought this was an interesting topic.
A lot of teams have good batsmen at 8 and 9, but in test cricket the bottom two tend to be a big drop off from that. I remember some lower orders in ODIs where almost everyone could be classed as an all-rounder, from New Zealand and South Africa in particular, but I can't recall a bottom 4 in test cricket better than this one.
Hogg at 8 averages 35 in FC cricket with a few centuries, and wouldn't be far off bowling all-rounder status. Lee at 9 averages over 20 in tests over an extended period and has been batting better in the last few years as well. Johnson's only had a short FC career but averages 26 with a few half-centuries, and has shown some skill with the bat at international level as well, and while Clark's FC record isn't anything special he looks a significant cut above your usual number 11 - more like a 9 or 10 in most sides.
Any better ones out there? Either in terms of skill or statistical record? Australia's tail a few years ago with Warne, Lee and Gillespie wasn't bad by comparison either, but I think Hogg and Clark are big improvements in their respective positions.
