It's long since gone. With top and middle order batting like England's, you really need to bowl out the opposition for less than 200 twice to have any hope of winning in these conditions. In fact it would serve England right for all the nonsense they've been up to in the tour matches if Mahela were to completely humiliate them by declaring now with a lead of 280 and two wickets still standing. I'd be surprised if England could get anywhere near 200.
Meanwhile the pollyannaists will continue to argue that top order batsmen who have been batting like tail enders and averaging in single figures or the low teens in successive overseas tours should be retained, because Greg Chappell once replaced a washed up Ganguly first with a guy who was never cut out for Test cricket in the first place, as he was basically helpless against the short ball, and then with someone who was even worse against that type of bowling, or because Owais Shah and Ravi Bopara have been tried and found wanting for England.
For pollyannaists, it doesn't matter if Bell and KP continue to average, say, 15 in the SC for the rest of their Test careers, because anyone proposing change is equivalent to the guy who decided that replacing Ganguly with two guys who were walking wickets against the rising ball was a good idea.
This house proposes that only intelligent persons ought to attempt to make analogies. Discuss.
