Actually Bangladesh is new emerging team which have some defecencies but in future it will be on the same level as New Zealand.
In both of them the atronger team is New Zealand so i is better chance for the Kiwis to grown up their points in ICC ranking and to be at top of the Rank if possible.
Yeah, it's obvious that NZ is going to win this. But Bangladesh has got some very special talent and can come up with some surprise. As they did in the past. They have beaten the best sides in the world like Australia, India, Pakistan etc.....
