Australian Cricket today

One can't help but notice how lousy Australian cricket is at the moment, can't get much worse.  It's obvious a lot of changes need to be made, but where?  In my opinion it's well overdue time to get rid of Ponting.  In most other sports if a team is doing real bad the captain steps aside and let's someone new have a go, why not cricket?  I think get rid of Ponting and Clark and make new, drastic times call for drastic measures
