It is not numbers that matters. They had right persons, umpires to do the job on their side. There is no faith in numbers when the right ones are out. That is secret of Aussies invinciblity.Once that was taken out the invinciblity ended.Even on 4th day of Sydney test Indians were ready to take the umpiring in their stride and move on. But they went too far in taking advantage of umpires.Once they crossed the limits they lost that luxury of biased umpiring and fell flat on back at Perth.Indians had hit hard where it hurts by keeping Bucknor out. Or else they could have continued to enjoy favouratism of umpires.
