We shouldn't be playing with 8 batsmen in the 1st place. It's pretty clear we needed Sunny in these last 2 matches. Also our #2 and #3 didn't do jack in the end. Promote Shakib or Nasir up to #3 since they have the ability to bat basically anywhere and have Anamul open with Tamim.
Also lets keep Riyad at #6/7. He's proved that he's more comfortable when playing down the order and playing with the tail. So why change that? He does that role pretty well. Don't fix what ain't broke.
