I'd say he has great potential, a little hype not bad but when he fails, and he will eventually because he's still learning, the administration will neglect to work him back up to an acceptable level. What i gather from the commentators is that having skills and talent early can be detrimental if it's not showing on field, cricketing boards tend to expect players to do well all the time and to bail out the team all the time, that kind of pressure and expectation hampers a players ability. He should be allowed to develop his own game, when he has a stable form then he can be pushed to do more.
just dropping him in a West Indies side won't make him or the team better. Too much patchwork within the team for players to play optimally.
I believe he can deliver on the hype, but without all the unrealistic expectations some people may have. He's just not that experienced yet.
