Not a cat in hell's chance that they would pick a batsmen like Jennings. They would be more likely to pick Bethell and tell him to do what he wants.
Historically opening batsman are there for a reason. To see off the new ball and the opening bowlers, not expose the lower middle order early on.
Stokes and the coach know better though. Have a slog lads, it doesn't matter if we don't bat 70 overs in the match and make ourselves look complete idiots in the ashes, as long as we're having a good time.
There's absolutely no balance with this England team. They have no idea when to dig in and graft with the bat for even one session.
