The team made misstakes at the drafts but yamato isn´t a bad coach in my opinion. His work with the team on a personal level looks good.
If I understand it correctly, the draft is not only determined by the coach. 
In this case the team has to work on the drafts and overthink the currently meta. 

I can understand that some fans being disappointed with the latest results but we should believe in this team and look forward. The split isn´t over and after a bad time we will come back stronger 👍
