The more you analyse England vs. West Indies and the more it becomes clear: it's youth against experience.
The Windies have eight World Twenty20 winners in their ranks, the majority of their squad is over 30, while England have only Plunkett who has reached that age (and he won't even start tomorrow).
The only question for Eoin Morgan is whether he bowls Plunkett or David Willey, and I'm sure he'll opt for the latter after his nifty hat-trick in the final warm-up exhibition.
Chris Jordan is a fantastic death overs bowler and deserves to be in the side due to his fielding, while Adil Rashid and Moeen Ali will be crucial. I wouldn't actually mind Dawson being deployed as a third bowler, like Williamson opted for for NZ in their win over India today, but I doubt England - despite their effervescence and youthful positivity - are that brave.
