The laws and attitudes have changed regarding racist taunts in all sports.
Yes...Aussies were the best/worst but have been bitten a couple of times so now are doing what was done to them.
As for who if not Ponting...Mr Cricket. Pup is too young. Hussey would be a good leader and role mdel to develop Clarke.
Mind you Ponting is in a very difficult situation. If we were losing 10 tests in a row then people wouldn't care what sort of things we did/said in order to win.
The brashness and arrogance that gets us to the top becomes the achilles heel also.
