I don't think the Channel 9 guys are anywhere near as upset as some people on here seem to think. The only ones with a big hardon for Australia are Healy and Lawry, and Lawry's mostly just tongue in cheek I think.
Greig and Chappell would be pretty happy to see Australia lose I'd imagine, and Nicholas and Benaud are probably more pure professionals.
Anyway, South Africa have been really excellent throughout. Well-rounded attack, every batsman except McKenzie has contributed at crucial times, and their fielding and general approach has been superb. Australia's batting has been disappointing and their attack has been up and down, more or less as expected. The injuries to Lee and Symonds certainly haven't helped.
The highest overall quality of test cricket I've seen since the '05 Ashes I think, and just like in that series, there have been moments where Australia have been on top and the result could even have been 2-0 the other way at this point in time, but the key moments have belonged to South Africa. For so long, Australia have dominated not always by winning every moment and every session, but by peaking at the right time and outlasting the opposition over five days. That's exactly what South Africa have done in this series. Conceding a first innings lead and then chasing over 400 in Perth they stayed in it, and with 6 wickets down and more than 200 behind in Melbourne they did the same thing. Well deserved wins.
I have a feeling Australia might win in Sydney and Hayden will do enough to keep his career going, if he wants to. Will be interesting to see though. If only Watson was fit.
