The problem is, that Holder is the only person (maybe) who agrees with whatever the board says, hence the captaincy.
Shai Hope is an interesting prospect, and can be chosen for vice captain. I know he is inexperienced but can be nurtured into one of the great wicketkeeper batsmen. His innings against England was a true gem and he has the capability to produce much more like them.
It doesn't matter whether or not he agrees with the board or not. What both Sri Lanka and West Indies are missing is motivation. Players need to be motivated and being able to push themselves to do the best they can.
For WI, Darren Sammy was an ideal leader. He motivated the WI team, and they were relaxed and enjoyed their game. Sammy made the massive mistake of talking crap about the board and his career is over. To me, the mood in SL is quite dull and there's nothing that is inspiring them to be able to show fight. WI on the other hand, they were inspired by that win over England at Headingley, and they are gradually getting better. A strong leader is essential in any team's chemistry. Holder himself cannot lead form the front and isn't able to inspire and motivate his troops. The board is a problem with selections but they have massive faith in Holder whereas he should rather be focused on his bowling than being captain. The board made a massive mistake on giving Holder the captaincy in the first place, and obviously that's immensely affected his bowling.
Shai Hope is a very talented batsman but he needs to make more runs instead of being judged on one Test. He is assertive, which is what you need one leader and aggessive. Holder is too defensive. Shai Hope could become the next Windies captain, but he needs to establish himself in the batting order and become a more reliable player.
