Tamim - long term, settled
Anamul - groom him to open with Tamim. The best option at the moment, surely.
Mahmudullah - how long before one of your most techinically adept batsmen gets to play at 3 rather than clowns like Mofees?
Shakib - does best at #4.
Naeem - I'm okay with him batting at 3, but I prefer Riyad. Or swap him with Riyad at 5.
Rahim, Nasir to follow, maybe Mominul in too.
