It's good to see some cricketing action. But already some of the WI players like Bravo, Hetmeyer and Keemo Paul have refused to tour ENG

We also don't know how many of the other ENG/WI players are not willing to play.
I don't see any specific reason in article. Is it because of pandemic or what? Well whatever the reasons, its big blow to Windies team as both Bravo and Hetmeyer are good cricketers. Still 1 month to go so they have enough time to rethink, let's hope they change their decision.
The exact reason for refusing to tour ENG is not known at the moment and yeah it will be a definite blow for WI as they don't have many good players now. We can only hope they would rethink their decisions. But if the pandemic is the reason behind their decision, I don't think they'll change their minds in the 1-month gap. The WI Board claim that the player's decision doesn't affect their future selection, so I just hope that they get a chance to take part in the T20 World Cup and not ignored because of their current decision.
