Interesting opions, what's your 11?
Bairstow can't and won't bat at three and keep. It's not sustainable and very likely to impact hugely on his batting, keeping or both.
Depending on the pitch, it'll go something like
1. Jennings (he may get a tough time from Roach and Gabriel)
2. Burns
3. Bairstow
4. Root
5. Stokes
6. Buttler
7. Ali
8. Foakes (wk)
9/10. (Two of) Curran/Broad/Rashid/Leach
11. Anderson
It will be about sticking with those who wom 3-0 and having the flexibility to adapt to the different pitches in the Caribbean. I don't see huge changes but do think that Roy will be given a go by the summer
