This was a strange series to be honest. South Africa baiscally played the first 2 tests with only 10 guys, with Duminy injured in the first test, and then Kallis in the 2nd, and then only batting.
I feel very sorry for Peter Siddle, he's by far the best test bowler for Oz, but he was over-used in the first 2 tests, partly because of Pattinson's injury, and the good batting by SA. If he played the last test, then the match could've been much closer.
but I think both teams have learned a lot about their own squad in this series.
Oz have learned that Quiney is not up to test standard, Shane Watson is a liability when not fully fit, Mitchell Johnson is an attacking bowler but can't keep the pressure going, and lastly, there is life after Ricky.
As for South Africa, I hope they finally realise that Imran Tahir is not a test-quality bowler and that Robin Peterson deserves his place in the tests. Faf Du Plessis is a wonderful addition and Jacques Kallis is still a fighter. Lastly, I hope the debate surrounding AB De Villiers and his dual role as Wicketkeeper/Batsmen comes to rest. He has now adapted to the role, and his century surely has to silence the critics.
