I also think the game change is really unpredictable, anytime any team can play bad or weak team in the list can show good performance. But the ranking should not be underestimated, things are very good. Because the current performance of that team also depends on the ranking, that is, the quality and condition of everyone in the team should be kept and practiced in the team.
I totally agree that ranking’s can be misleading in this format, and when you look at India one may feel that they’ll probably win the upcoming T20 World Cup, but the reality is that they’ll not win because of their poor bowling. Furthermore this tournament requires strong batting, and again team India’s middle order looks vulnerable and hence if one is planning to wager on them then I would advise not to, because I feel that they may lose too easily against their opponent’s.
