For me, this India - Australia series is all about momentum. For the Aussies, it's the much vaunted Ashes momentum, and according to Lord's Twitter, India are hoping to get momentum for when they play England next year.
First the momentum was with Australia, then with India, then back to Australia, then returning to India, and now it could be argued is back to Australia. It will probably end up with the umpires.
So what's the importance of momentum. Australia obviously can't believe in it, as they picked the hardest team to face ahead of the Ashes (and probably ending momentum), whereas England often pick the simplest of games before Ashes series.
Does momentum play any part in Ashes clashes? Yes, it does. If England win the first two games, chances are they'll find the next two, as they'll have the belief and confidence created by their great performances. As seen with Australia's whitewash in 2006/7. How different could the series have been had England won in the 2nd test? Momentum does play a part - a huge part in fact. But India-Australia is not momentum. Come November 23rd in Brisbane, chances are Andrew Strauss won't be thinking of Mohali. Even if Marcus North is thinking of it, while sitting at home.
