I haven't watched the batting of Heazlett and Renshaw but it sounds encouraging.

The main issue for Australia is a lack of technically competent batsmen (even batsmen with decent averages but lousy technique used to batting on roads).

What the selectors need to do is what England around the millennium. They prepped themselves for the long haul by identifying technique and talent (even if it wasn't getting the best results) and persisting with it and encouraging it. This sometimes meant favouring such talent over batsmen who were getting more runs but had technical trouble which would probably catch them out at Test level.

Basically, Cricket Australia should do everything in its power to send Heazlett, Renshaw, Patterson, Bancroft, etc. to play county cricket in England (being aware that Renshaw was born in England). Greg Chappell was playing county cricket very young. Basically, we need those batsmen to learn how to play the ball later when the ball is doing a lot (because it doesn't do jack shit most of the time in Australia and our batsmen are at sea when it does anything). Use Chris Rogers as example.

Lehmann's already doing this.

If we can build a solid top-middle order with young batsmen who can play in any conditions, then there's already Warner and Smith (great in Aus but hit and miss overseas), then we're going to have some kind of a decent side.

And less likely to be humiliated each and every match we play in England and the subcontinent.
