I think, in general, there is a lot of sense in what you’re saying. We don’t want to be chopping and changing the team or the batting order as much as we have been doing and this is, probably, at least part of what is causing inconsistency in our batting performances. About the only constant is Root at 4 at the moment and everybody shuffling around trying to solve our issues at 3, is having a deleterious effect on the form of guys in the lower order. We should hit on a team and stick to it and I would say that:
Burns, Jennings, Denly, Root, Buttler, Stokes, Bairstow, Ali, 3 seam up bowlers
Is probably about right.

That is Keaton Jennings Test match performance over the course of his career. He averages 17.7 in matches in England over 18 innings - he can’t play the moving ball and he has been shown up here as struggling against pace. Starc and Cummins are going to eat him alive. He looks like someone that I’d be happy to have go to the sub-continent but facing seam up bowling, he’s going to struggle unless he fixes some fundamental technical flaws. For me, the general ethos of what you’re proposing is right (particularly if you can be sure you’ve identified the right players) - but I think you can bed in the remaining 10 players in the team in the right places in the order, and still say, “he’s not good enough - let’s see if we can find someone else”.
Now - my get out of jail free card. England’s next test isn’t until the end of July (against Ireland) and there will be a lot of county cricket to be played. Jennings doesn’t play ODIs, so he should get as much red ball time as we can give him in the early season. If he starts scoring some runs and is the best of the options available to us, I’m not against him sticking. On the other hand, that’s also a lot of red ball cricket for other guys - Holden, Gubbins, Bell-Drummond, even recent discards like Stoneman, to also score a lot of runs. I’d hold the #2 position open in the side for the moment and select whomever performs best for us, rather than be wedded to Jennings in the name of consistency.
Roy for me is an utter non–starter but better judges than I, at least people I have some time for in the press, are talking it up which is usually an indication that someone in the England selection camp is talking it up as a possibility or they’re seeing something that I am not.
104-5 in the Caribbean. England are going to win this comfortably, barring an act of God (either via weather or a West Indian partnership being touched by him).
