Alarming Condition For New Zealand

It has been a long time for New Zealand to win a series comprehensively against any top team in the world.

They in the past were tough one to crack but at present its a different situation for them. This Year they have lose in ODI's against two big teams WI and South Africa by margin of 4-1 and 3-0 respectively. This really make them to be least favorite in this year T20 world cup final, despite being the semi-finalist in the last ODI World Cup. 

They have got one of the best players in the history which creates pressure for opponent teams. Although right now they have a good quality side on paper but somewhat they are not pumping up. They need to win some matches against tough sides to get that momentum back. One more thing which might hurting them is the frequent changes of coach, Mike Hesson as appointed as the fifth coach for New Zealand in last four years. But seeing the record of Mike Hesson it looks like he might be the game changer or could be the great conditioner for New Zealand team. As this guy has the experience to coach New Zealand-A team which will really be a key factor for them. There batsman such as Martin Guptill, Macullum, Ryder and others they need to put some effort or else it would be the alarming condition for them.
