Stop blaming the NRR

One thing I can't understand about our senior sports journalists, commentators etc that they start placing all the blame over NRR regarding early exit from CWC19 but the fact is NRR is a tool, should I rephrase; a predicting tool use to analyze your strategy and if require making little bit of tweaking, which Pakistan was, sorry to say 'sans'. What was the purpose of the management, specially the coaching staff and the management who were accountable for them, bring them into accountability and ask this simple query that when you knew Pakistan lost to Windies with a gargantuan margin, than why in other games, we didn't go for quick end of the games? If I were at their place it was a criminal offence because players do not know much about excel and NRR, this is the job of management and computer analysts working under them therefore it is simply neglegence from their end thereafter start a culture of computer analysts in domestic level so that when our players come to international arena, they are accustomed to these stats because they had been in that culture for long.
