When will the Bangladesh team learn?

Why the weakness of the Bangladesh cricket team appear in the last moment of the game?  Why Bangladesh makes the easy match difficult?

Bangladesh vs Afghanistan match held on 14th July was full of romance.  After many dramas, Bangladesh won the match, but some questions remain.  The 17th and 18th overs were exciting for Bangladesh, but in the last over, Bangladeshi batter made mistakes as usual. Mehidy Hasan Miraz started the drama!  Why did Miraz hit the bounce ball for a six after hitting a four?  The fall of the wicket while hitting a six!  Couldn't have Miraz take a single run?

After Miraz, Taskin Ahmed made the same mistake and gave a catch to the wicket keeper and returned dressing room!  Back to back wicket!  Meanwhile, the non strike batter Towhid Hridoy is sitting hope to take a strike!  Any  incident could have been happen because of the mistake of Bangladeshi batter!  It cannot be finished by telling the fans how many drama they had to watch while taking 6 runs from 6 balls.

On the 4th ball of the 20th over, Nasum again walked in the path of Miraz and Taskin!  Hitting the ball to the third man with a catch Nasum got out and back to the pavilion. What a come back for Afghanistan! Karim Janat got Hat-trick! Now two balls left and need two run to win!  Luck was  in favor, next ball was timing well by the new batter Shariful. Bangladesh win the match dramatically.  But an accident could have happened!  None of the last four batters had the mindset that Tawhid Hridoy was sitting on 47 runs at the other end.  If they rotate the strike, maybe it would have been a fifty for Towhid Hridoy!

However, they are all basically bowlers!  So it is normal to make such a mistake!  But when an experienced batter makes the same mistake, what do you say?  What does history say, do you remember Musfiqur Rahim and Mahmudullah in the T20 World Cup 2016?  The Bangladesh team created exactly such a situation in the T20 World Cup 2016 vs India!  Bangladesh lost that day!  Because luck was not in favor like today! Shouldn't we learned from these mistake yet? Hope Mussy Mahmudullah learned but we? It is a example only.

There are many such matches in the history of Bangladesh cricket where Bangladesh has made easy matches difficult with their own hands!  Bangladesh has lost easy match many times by making the match difficult!  How many mistakes will Bangladesh made with a straight hand at such a crisis moment?  When will they learn?
