These are pretty fair assessments tbf by yourself & @anon26275971 . I don’t ever like seeing a player getting dropped when in a run like this and probably end up hoping that next time he steps up to the crease, he’ll cream a half-volley through the covers and all of a sudden everything will be fixed.
It is clear that his head’s gone in a technical sense and he’s thinking too much ahead of each ball about what shot he’s going to play rather than playing on instinct. That pre-meditated scoop shot against Bangladesh was horrific.
Perhaps the mental side should be what the decision is based on. If he’s really feeling as though he’s a burden on the team then by all means, pull him out. Equally, if he’s showing a determination to battle on and justify his position then I do think there’s a case for backing him for the semi-final and (hopefully) final ahead of the T-20 domestic competition and hope that it comes good.
