Kiwis whatever their commitments, their nation comes first. McCullum transformed a weak team into a world beater and fighting unit. For them playing for the country is a moral responsiblity. He already had contributed his bit and knew there are more who could do better than him. Same thing can be said with Ronchi. For them playing T20 leagues is less pressure. If it was not for McCullum, Fakhar Zaman would have never played for Pakistan.
ITs a shame for us that in recent years foreigners like Woolmers, Mickey Arthur and McCullums have contributed more for Pakistan cricket than our seniors and former cricketers like Inzamam. The foreigners decisions have worked more than our chief selector contribution in forcing his coward nephew Imam[who refused to play in the NZ conditions fearing his place] , Maliks, Akmals and Hafeez, in the side over deserving talent.
They don't make their countrymen happy though. When Grant Elliot was seen watching the match in the crowd with his family. Commentator Ian Smith made a nasty comment calling him a 'T20 mercenary'.
