England seem to be loathed to drop batters, regardless of how poor their returns are. It seems no-one gets dropped until they’ve had their technique ripped to shreds in the media. Back in the 90s/early 2000s England’s batting order got chopped and changed relentlessly, but I fear we have gone too far the other way now, with hopelessly out of form batters continuing to be picked.
Same can’t be said for bowlers, especially spinners. One or two bad games and you’re out.
