The last test vs WI isnt simply interesting because it's test cricket, but also because some critical positions are up for grabs.
Whilst most focus has been on Australia's lack of a spinner and choice of 3rd paceman, the choice of who partners a presumably fit Hayden next time out is also contentious
The serious contenders seem to be Jaques, Katich, Watson and, to a far lesser extent, Hughes and Marsh
Here's my summary of the situation
Jaques - looks like he's struggling, verrrrrrrrrrrrrrrrry ugly, but the guy has a very good test and fc record AND has pulled out a big one today under great pressure
Katich - another incredibly ugly player who was gone for all money last year but has bounced back with a stack of fc runs, is scoring runs out of position, handy bowler BUT shells catches easier than peas
Watson - IMO, best bat of the lot but why sacrifice him as opener
Hughes and Marsh - score more runs
Personally, I'd continue with Jaques.
