They learnt nothing from the past

During the second T20 match played against Sri Lanka, I believe the Tigers lost the match purely due to poor decision making. If dew was such a big factor, why didn't they bowl first? If Mashrafe is Bangladesh's best express bowler, then why didn't he take it upon himself to bowl the last over? A good bowler is one who is capable of bowling in any given over. I believe Farhad Reza did not have the experience or pace to bowl the last over. Furthermore, why weren't there any close-in fielders to prevent the boundary when the last ball was bowled? I believe our captains need training on how to make good and correct decisions on the field.
     As far as our batting is concerned, I believe they have learned nothing from previous games and past mistakes.
