With apologies to the pacers wreaking havoc, spinners baring their fangs, and batters bossing around, it would be fair to say that the Indian juggernaut in this World Cup is not just about explosive performances on the field. The great Wasim Akram thinks it would take an "extraordinary effort" to halt India's charge but reminded about their ICC title drought every step of the way, skipper Rohit Sharma and his ambitious colleagues very well know that their job is only half done. India became the first team to reach the World Cup semifinals with a 302-run rout of Sri Lanka on Thursday night, their seventh win on the trot. They are in the middle of a dream run but Rohit and his men will eventually be judged on their performances in the knock-out stages, their achilles heel over the past decade.
