rubel is a banned ICLer...it was a poor move on his part. everyone else is understandable if not condonable.
to be honest, the only mistakes the selectors made was including nazmul. but this is a part of the original mistake. they already went to bring one team, and so there is no point in sending nazmul back if they aren't going to bring sajid.
the main problem with this is panel is that they had their revolving door for the 3rd (now 4th pacer spot). first it was sajid, then dollar, and now nazmul and robin. sajid should have been persisted with.
