My find is 'Shahriar Nafees' !
I never ever thought of him being such a coward and sissy player. When he had a great chance to show his captaincy abilities and power hitting batting, he just hid in the dug out. Not a single try to make it happen. Its time to put his cricket kits in the shelves and never ever think of further career in cricket, be it as coach, consultant etc.
And for promising players, still no one makes to my list. All of them showed some glimpses but that does not impress me much. We never had any doubt on their skills but no one really stood out from the crowd and said ' i am the real big thing for Bangladesh Cricket'.
