Not sure how much England can take out of this series. Had the opportunity to see what Morgan can do but didn't give him a chance. We will probably get some talk about Prior doing well up the order, but i'm not sure that is anything positive for the future. Haven't really solved any problems (bowling at the depth, scoring quickly in the first 15 overs against half decent bowling). England are pretty good frontrunners in ODI cricket, just not much good when the opposition puts up a fight.
On the other hand, On paper West Indies have the 3 best ODI players taking part in this series (Chanders, Gayle and Bravo) as well as 2 of the best 4 bowlers (Taylor, Bravo). All things considered, especially with England missing Flintoff and Pietersen, West Indies should have expected to win this series. Obviously you can't predict attitudes, and West Indies' has been disinterested at best, which is why England can't take much out of the series apart from the win, maybe a bit of confidence.
