Most of the young players of Bangladesh might've got inspired by him. As we say Tendulkar as the God of cricket, Shakib Al Hasan is a person who had to be praised for what he had done for the Bangladesh cricket. There'll be issues between the players and the cricket board. His ban for the reason of making deal with a gambling firm have received warnings earlier. As said by @Sithara007 here we can't blame anyone. He's near his retirement, before retiring he needs to be given opportunity in all formats of cricket.
The one-year ban handed out to him was unfair, IMO. There is a lot of involvement from bookies in the IPL, and even franchise owners were involved in fixing matches. But in the end, only two people got punishment for their role - Sreesanth and Shakib. And no proof was found against these two players and they were acquitted by the court. During the investment process, BCB never offered any sort of support for Shakib. Anyway, now he is well past his prime and the management need to make sure that younger players are able to replace him in the near future.
I think we have talked about this before. But I am going to say this again because I want as many people as possible to know this. The reason why Shakib Al Hasan was banned was because the Bangladesh cricket board wanted to remove Mashrafe Mortaza from the captaincy at that time. And they were not being able to do that with Shakib Al Hasan having an influence.
Of course, I also think that BCB actually provided the news and the proof (by proof I mean the WhatsApp messages that Shakib Al Hasan got from Agarwal in which Shakib Al Hasan never even replied to) to the ICC. And Shakib Al Hasan was not banned because actual evidence was found about him, fixing matters or anything. He was banned because he was just approached by a bookie. So after that ban, Shakib Al Hasan went to England. And at that time, the Bangladesh cricket board removed Mashrafe Mortaza from the captaincy, which was basically his retirement. The problem was not the BCB president I believe. The problem was the others on the selection board and the directors like Akram, Nannu, etc. They knew very well that, if Mashrafe Murtaza actually had enough power over the cricket board, which I believe he would have had eventually, they were in trouble because they were not doing anything good for that team.
