The reason people like Nicholas write stuff like that is not something personal against West Indies. It's the fact that they are quite ignorant about cricket teams outside of the major nations. I don't want to make this about Big 3 but guys like Nicholas, Chappell, Bhogle or Channel 9 commentators watch more cricket involving India, England and Australia, and as a result are more well versed with players and records of those teams. They barely watch or keep track of cricket involving the other teams.
Outside of that, they are poorly informed and can't be bothered to do the research. It used to bother me at first but now i am used to it. Most of the times, these guys can barely name any of the Pakistani or Bangladeshi players.. During the World Cup 2015, Healy was referring to Pakistan players as 'that guy on the left, the tall fielder' etc.
So, basically when they write these articles, names like Root, Kohli and Warner are what they are familiar with as they have seen more of their cricket.
