with the right coaching set up it has strong potential. the batting has had major issues and without proper help it wont change.
Would love to see us bat positively and look solid.
As I have said elsewhere, I don't think McCullum will bring an ODI mentality to this; instead, what I think he will work on is getting each player to express themselves in a positive manner; even if that only means a more active approach to looking to rotate the strike amongst the top order batsmen.
Somewhere England have struggled since Cook went is in their pacing at the top of the innings - it has either been utterly frantic (Roy, Crawley on occasion) or you have had batsmen looking to dig in for the long haul and getting themselves into a dead bat dark alley (Denly, Sibley, Burns, Hameed, Lees etc). Any one of those players could do a much better job, but it requires them to be able to maintain a rate of scoring, something Cook was often underrated for.
